We all need to start somewhere and I think it's good you started with something simple rather than trying the most complicated thing out there and then feeling bad because you didn't succeed as well as you had expected. Like the others said, in the future you may want to try making an abstract background, also try fooling around with the image and text effects! :D
I like the angel (except for the red face and glowing eye bits). I think it would look better if it had an abstract background (something similar to the one in my sig or like what Maladrin does), and maybe a change of font. Oh, and stick a border on it. But that's just the way I would like to see it... You may have a different taste. :)
