Early morning talking time. 

[@Cmmelody]: Uh... Funny enough, I think Shino might be [i]too[/i] low power. There's a few reasons for this, but here are a few:
[list][*]Chakra, as noted explicitly within the Naruto world, is a byproduct of external factors being inherited by the entire human population (and more). It's not something that you could map onto other similar power systems (e.g.: HxH nen, Dragon Ball ki, any fantasy that uses an internal mana system.) That's only further emphasized when speaking with regard to how specialized Aburame insects are with regard to chakra specifically. Can't do much when a good chunk of your utility is tied to the presence of (or removal of) a resource that others don't have. Even if you do map it into internal magic systems, it's still super limited in scope, and that's if we ignore the oddities inherent in smashing two discrete systems together. 
[*]It's pre-Shippuden Shino. He's super untested in the field, and from what we get to see of him, uh... There isn't much, even if he's above average in his field of teenagers. Shippuden Shino might be able to stick it out more, but reliance on breeding and raising insects in either case gives him hard finite resources to use, at least until things theoretically stabilize enough to fix that problem.
[*]Development time because it's specifically pre-Shippuden Shino being nonexistent coupled with no one else familiar with how the Aburame do things means his ability to get stronger is super stunted, even if we once again disregard the chakra issue mentioned above[/list]
Also, and this is a more personal opinion: that form just needs more fleshing out in general. Feels a bit barebones to me, and it doesn't explain enough stuff to people who might not have seen the IP (even if the burden of research would fall to those who have, the better other players can understand what's being provided the better).

[@Xaltwind]: Existing, no OCs, no customizable characters unless there's a widely agreed-upon default (in which case you use said default).
