When you blur parts it normally means you are creating depth. But you dont have a real background to create depth with if you know what i mean. Next thing try not to border your work but its not really something bad or good.
The text placement for v4 is the best though you still need to work on the text (dont worry about the text at this level)
Blending is fine i guess and i dont think you quite got keros tut ^^ maybe i can team-view it to you if we both have time..
