I'd say you'd need more variation.... The art style forces you into doing the same character but with different hair and clothes.... Steel and Black Shade have the same face and body shape which is something you want to avoid with the Antagonist and Protagonist unless there's a good plot reason behind this....
Or unless you're drawing moe...
Indeed....
And I'm sure you'll do well because you're good.... You've drawn stuff that has variation and all that but you just haven't brought it into your Team Powerz art style....
