Yeah I can definitely tell you have that niche for Japanese anime style. You are a potent one indeed. The pictures you drew were really good. However for the first one or anything like that, I would put less emphasis on the eyes. The anime style does have big eyes, but those are a bit too big. Other then that... thats about it... nothing else....supposedly only thing wrong.....the one thing thats off............ LOL
Heres a picture I fabricated out of a picture of Naruto and his hero Yondaime (4th Hokage) from the anime NARUTO:
I took accents and elements from pictures of both of the characters and blended them. PM me sometime, MrCoffee, we can discuss design and art and anything else you wish.
