Heh, this is not even similar to your designs. I wonder how people can be mistaken. It's overdetailed and completely different than yours! That reminds me of Naruto Ryujinki (I hope I wrote it right x'D), not of average ninja clothes. Your designs are pretty simple and that's what I like in them. I have seen many bad designed OC with very impractical outfits, it's very rare to see a good OC Btw, these 'awesome' and complicated outfits would be PAIN for Kishi to draw x'DD Just imagine him sitting and drawing every small detail on every single page Priceless!
I wondered too XD and I thought the same about the Ryujinki-style (you did write it correctly XD) especially because of the jacket. And thank you so much I try to keep them as simple (and Naruto-like) as possible, because of the exact reason you wrote...how the fuck should anybody be able to draw a character with seven billion details for almost 600 chapters on every single panel? XD OMG, just thinking about that makes my hand hurt XD
Actually that's not my design, ~MickelHiwatari designed it, I just drew the character =3 I really do think about designing clothes as a sidejob maybe XD I have a lot of fun designing stuff, but I guess I won't do it professionally (also because I can't sew )
