Need feedback! :(

Okay, I played around with Photoshop for a bit - and it turned out real crappy.
So yeah, I'll go back and try to do better. But while I do have a friend who is pretty damn good at doing this kind of stuff, I'd still appreciate any feedback and advice you could give me.

Here goes:

No nudity but there is a bikini.

I'm pretty happy with the left part but not so much with the right part.

(again, I think it shouldn't be a problem but you never know...)
This is the original pic, I tried quite hard but I couldn't get it any better. Any advice?

She's . . . uh . . . missing a hand.

Have you ever checked out the tutorials at Worth1000 for this sort of thing?

I know. But I'll blame that on the original pic.

Eek...the website is ugly imho but I'll check it out. Thanks!

Still not happy with her left side...
