Shy girl at the beach

Well... I finally got photoshop and this is the first pic I use it. It didn''t come out great... I still have a lot to learn about Photoshop, but for the first time without much help, I guess it didn''t come out that bad.
The backround was blank so I put a picture of the beach I found on google, I guess it gave my drawing a little something ^^
PLEASE! I beg for comments!
Thanks for the atention =D
