1) I like the background for you being a beginner.
2) The pic is bad quality. I know you clarified that already, but the pic is the main focus of any wall.
3) The text really needs work
4) It might look better without that bar
If you have any questions or just want me to further elaborate, just IM me on AIM at SWPsean.
This is great for your first wall. You just need to keep working on basics of sigs, such as cropping, backrounds, and font and text work. I bet you`ll be a great wall paper maker one day after seeing your first works.
