Please Stop Raining...

Another attempt at single layer painting on Sai. I think I did a lot better on this one, mainly because I avoided showing the eyes. That seems to be the part I'm having the most trouble with. That, and the rest of the body... 
Um, this is my character Kyna. I have no idea why I drew her in such a sad setting. She doesn't really have normal emotions, so I can't see her getting sad like this, but oh well. She fits just fine.
If anyone has any experience with single layer painting on Sai, would you mind giving me a few pointers? Thank you!

Kyna belongs to me. Please don't use without my permission. Thank you.
