[i]-That is a weird ass hammer, you'll have to clue me in on its uses or if it's just light and used for close combat.
[/i]
me: At first I wasnt too sure how weapons would work. But reading the rp I got a few ideas. Miro tends to use the hammer in close combat. To block and parry with its hilt or to swinging it around in a circular motion. I was thinking of incorporating maybe mid ranged attacks by using the hammer as source of shock wave that would dis balance the opponent if slammed on the ground. Including the enchanting of direct hits, as in amplifying the destruction if the hammer directly hits the opponent. The down side would be that MIlos is slow compared to some other correctors, and simply prefers the close combat.

[i]-Now onto the background section, it was a bit hard to read in terms of some sentences just sounding stiff so you may wanna try reading it aloud to work out any kinks that deal with flow and grammar. I know you mentioned you did some editing but it does need some more work, some misspellings and re-wording of sentences...
[/i]
I will do it. Its so annoying to read it myself at times as I myself end up cringing to some of the things I wrote. ^^; In posts its easier, as I dont have to focus on a whole life story with 101 things, but just on a handful of scene 
Thank you for giving me a chance to fix it. ^^

Then a question I had was regarding his change in demeanor after he came back from visiting the Balkans, he seems more out going which should be a good thing, why would his parents move away from the man who was helping their son? Only to have him begin to act out because of moving away in the first place? Is the parent (grandfather of your character) of the kid's parents not on good terms with whoever his kid is? (Miro's mother or father, whichever side the grandpa is on)[/i]

Me: The grandfather would be on the mothers side of the family.
And I was thinking that part from Milos perspective. In his eyes at that young age he may have felt that his parents didnt want him to be influenced by his grandpa as much as he was. 
In truth it could have been several disputes, along from possible not fully approving his daughters husband in the first place, to some money problems. The father then moving with his family for a better job and on the plus side not having to deal with the extremely stubborn man. Leaving their son constructing the story in his head that it was because of him enjoying more the time with his grandfather then with his family. Of course once away they wouldnt go visit the man ever weekend, but actually prolonging the time between the visits, which only strengthened the ideas in their sons head why they moved away.

[i]You also mentioned him having bad influences such as bad friends, would these be other bullies?[/i]

More like friends who skipped classes, stayed in the street. Thinking school is useless. Sneaking around buildings in construction phrase, and places children were not allowed at all. Dont see Milos sticking with bullies who would beat anyone up at that time. I can see him get in those years in some fights, rarely but could happen. More on the side of brawling then something seriously. 

[i]. In terms of his geographical location, I'm not sure if I missed it or not...did you mention where his grandfather lived and where he lives now? [/i]

Well, I just mentioned the region not the exact place. His grandpa would be coming from Serbia. But he would have spent his life in Japan, even now he would still live there. At some times the grandpa would go visit his home country but it wouldnt be all too often at all.
When it comes where in Japan the old man lives, anything beside Tokyo would fit. For example Osaka, etc. 

But I did left the option open that if Miro's grandfather died, his last wish would be to be buried in the country he comes from. Serbia, meaning Milos could be there for some time. If the geographic fits the story. If not then Milos could just be in Japan the whole time, just in a different city.

[i]I know he took a break to help his grandfather and he'd like to return now. Would you want him with our group as a new face (someone they know but don't work with) or someone who has been in the group but is returning? [/i]

Personally, both way could work for me. But if asked for preferences. I would say that my preference would lay in, the situation that he worked with the group before he took the leave for a year or something, and now would wish to surprise them with his returning. 

[i]And how old is the grandfather? Considering he's ill, I assume in the 90s?[/i]

Considering the status of healthcare in the roleplay, it would make sense him to be 97 years old.

[i]Anywho, just some feedback. ^^;[/i]
No problem I love feedback and pointing out my mistakes so I can improve all around ^^
And thinking even deeper about my character.
