Atlantica Sora and Kairi

Yay! my first KH fanart! This picure sprouted from a fanfic idea that I had, where Kairi goes with Sora and Riku to all the different worlds on some new adventure. (Riku is conveniently somewhere else at this point, mainly because I wanted this to be a SoraxKairi moment ^_^) and I was imagining how Sora would react at seeing kairi in mermaid form. Nervous blushing Sora + oblivous Kairi = uber cuteness!!!

I do plan to color this eventually, but I'm so worrid I'll mess it up if I try and color it, because I don't know how to do all the lighting and shading and color tones and whatnot to make it really look like an underwater scene. Ah well. I'll get the courage to try it eventually. lol. Any tips in this area would be great!!!
