Alright so this is how I'll do this; I'm going to hit you with a list. Beside each bullet with be (+) or (-); positive or negative. I'm not one for going into details, especially when it comes to someone else's character sheet. I find it hindering to the creative process. The only time I'll go into detail is if there is something I have an absolute problem with. So let's begin. 

[@OneStoryToMany] [list][*] ([b]+[/b]) I like the profile overall. You're definitely in the acceptable range. 
[*] ([b]+[/b]) Your Nen ability is simple but powerful. Makes sense for an Enhancer. 
[*] ([b]-[/b]) Birdy's baptism by Nen is a tad iffy to me. I'm willing to let it slide, why not. Hunters are extremely rare. I think it was mentioned that out of all of its population there were only 661. Nen Users are around the same, maybe more, it would rare for them to know the [b]truth[/b] of the concept. If not Hunters or Masters in their own right I think her skill would be greatly diminished. I'm skeptical of her being hit by a Nen User in the mafia and surviving at all, unless she was amongst a battle involving weak Mafiosos. Seems more likely. Very, very dangerous but plausible.[/list]

[@LemonZest1337] [list][*] ([b]+[/b]) The safe route is never a bad route. Your personality and aura type is perfect matches. Nen ability is simple but cool. 
[*] ([b]-[/b]) I can tell you allowed your preferences to shape your character instead of the world. This is not a score against you, promise, just something I noticed. 
[*] ([b]-[/b]) Which leads me to my final negative. The incident where she fell into the [i]toxic[/i] pit. That would def do more harm then good in this universe. It would be more acceptable if she had been born with some genetic mutation. Also go into detail about how fast and strong she is, as well as her healing factor. We spoke about this over discord. (Did you know there is a mutation that makes people grow indefinitely ;) [/list]

[@Tenma Tendo][list][*] ([b]-[/b]) I need you to go into details about Sora's Nen abilities. I understand the Tarot Cards but just how advance is she in Nen? She would have to be far more talented than Gon and Killua and they were 1 and 10,000,000. You could go the route of having three, perhaps four abilities with your Tarot Cards but I don't think she'd be good at much else. In considering this criticism, [b]think about the match between Hisoka and Kastro.[/b] Her training to take the Hunter Exam couldn't be that extreme, not enough for her to pass it with flying colors. Hmm? I'm not sure how to handle this but I'm on the verge of saying she failed. She'll need more meat and skill if she wants to pass as she currently is.  The Hunter Exam is yearly, do debate me if you believe she could have obtained the strength in that timespan. 
[*] Also I need to know her age. Its not something you can keep hidden when it comes to this game. Mostly because I need to compare her years, talents, natural abilities, and Nen potential to her age. Its kind of a game of assumption. 
[*] ([b]+[/b]) Nen Ability and Personality is fitting.[/list]

At most I'll be accepting talents on par with Gon and Killua.
