It looks like watercolor! SO KAWAII!!!!! I wanna be adopted to!!!! Even if it is by Riku AKA My Husband. ^_^ I am SOOOOOO Pathetic!!!!! *Hits self in head with 'Marble' Muffin* Here.... you deserve a Muffin *Gives Sumi a reagular Muffin* Enjoy!! DO MORE!!!!!!!
I think your coloring gives an extra soft look and feel to your pictures. It gives the picture a more gentle mood. I really do love your style with Riku, it brings out the little child in him!
