Jillian at the Ocean

If there is anything that can be done to improve this piece, let me know IMMEDIATELY! Like I keep saying, DO NOT FAVE AND RUN!!!

I don't feel too good about the ocean, though...If anyone has any suggestions or tutorials for me, that would greatly be appreciated! I tried using my Goggle-fu to look for ocean surfaces done in photoshop, but erm...Well, you get the idea...

Anyways, the character in question is actually the protagonist of Calamity. Figured I might as well start drawing some more things in regards to the game, since it is something I'll be making in the future. She works as a model to pay her rent and to take care of her 8 year old sister, since her mother passed away. She is 18 years old, loving, and caring, but has a short fuse at times. She has a long-time girlfriend named Leah. She is a half-demon (sounds Mary Sue-ish...Damn...I should really change that), however, her powers only come out when she is fighting, and since she hates fighting...Well...Let's just say her demon side only comes out when she feels threatened. Over the course of Jillian's story, she learns to control her other self at will, switching between her two forms. I'll have to draw her in her other form soon.

Just so you know, I found some really great brushes from:

Unfortunately, I tried drawing clouds many different times for this pic, but nothing seemed to work. I was having opacity issues, program issues, etc. Hell, even finding a damn tutorial turned out to be a pain in the ass! Thanks again,
