Reference sheet for my Naruto OC, Ikuno Tsukino. If you haven't noticed I changed her hairstyle a bit. I’m quite happy with it even though the change is rather subtle (I just moved her bun down), but I think it makes her look more professional and ambiguous (gender-wise).
I really do love her design and your style too. You have a lovely character, with a wonderful personality & simple design (less is more after all) especially the clan symbol (I was never a fan of fancy smanchy symbols) well done. I agree with what ~signora-sole said about Ikuno and Haku there is a massive difference (for one Haku looks more girly than her)
One of the things I think about the clan symbol being so simple is perhaps they're a very ancient clan and have roots back to the beginning of Kirigakure. It would be neat if the Yuki clan (Haku's bloodline) was also a sept of the Tsukino's.
That would be a nice touch to add the clan and it would make perfect sense for the symbol to be so simple since they wouldn't have many "competitors" to design against back then Making them a sept would give you some room for designs, playing with things and help development with the clans history.
Despite what people say, I see really big difference between Haku and Ikuno... First of all, Haku's hair is lot longer and brownish? At least from what I see how he is portrayed. Plus Haku's bun is actually higher than Ikuno's :/ You have a good knack for designing proper outfits for your characters, tho ;w; And her character suits perfectly for her job.
