The background is alright for your second. You over-used text and you need to learn how to blend the render in.
Try setting the renders opacity down. Then take the eraser and set it toa really low setting and go over it a few times and less text= better text. Like said above. And most of all, have some patience with yourself, dont ever. ever. rush through a tag. Even if you have to come back to it the next day. <3 ~merz
It's a ton better than my second sig, your best bet is to check up on some tutorials on blending and abstract brushing... and like mezrec said less text is normally better.
