Woow, this is some very good art. I'm sure your friend will love it! I mean, you got yourself a great composition there: nice perspective, awesome style, beautiful colors...everything is arranged in a way that by just looking at it creates impact. I think light and shadows complement each other correctly, and your bright background is sure to guarantee contrast and impact. The manga stylization looks great to me, specially her hair and eyes, wich no doubt are the "spotlights" in her face. Maybe you should check anatomy a bit, but it's nothing to worry about. Now, that's a deviation to admire. Congrats!
This is the one that started it all, the one that made me choose you for my primary artist for my works. The style, the colors, the awesomeness, it really shows your skill as an artist and I'm glad you drew it. It was the perfect beacon to find you with.
Looks awesome and some nice shading and coloring. My only point is that i think the tattoo should have more shading in it. No tattoo artist doesn't shade in a rose to give it depth! still looks really good tho!
