Work In Progress.

Work in progress, how could i improve this? I know I still need to work on depth and blending, how should I go about doing this? There are still some serious flaws on working on aswell, but I am determined to make this decent.

It looks like you tried to create depth with the background. It's not really working if that was the intent. I'd try blurring and sharping it a little. The render is just bad quality. You can almost see through her in some areas it looks like it was a picture from google that you went around with a soft brush trying to render it.

Note the semi-transparent boxlike line going through her wrist.

Also the backround doesn't mix very well.
