Team Dark by @Biscuits (Elli Gibbs)
Yeah, it's Team Dark. They're my fav team on Sonic Heroes (excellent game that it is); I almost have all of their A ranks! Anyway, this pic was originally just Omega (drawn with no reference, hence his messed up legs; I had to make it all up!! o.o), but I had extra room and added Shadow and Rouge. Omega's arm-cannon looks scary.
I wish I had an arm cannon.
I like this! Team dark does rock, but for some reason, I like chaotix better, no offence. Omega is pretty good since you had no reference, the highlighting and shading are pretty good. Perhaps make your lines bigger in some places, but they look fine how they are now. Try to make the shading a bit more smoother, using a blur, or smudge tool.
