If you're gonna tell him its sucks, at least tell him why (no ofense)
the most noticeable thing is the poor quality of the render (both of them).
you can get better pics
HERE
or you can get pre-cutted renders
HERE just make sure you credit.
The text is pretty simple, you should try to get different and better fonts in
www.dafont.com
The background is also very simple, maybe you can spice it up by blending one picture in the back and having one main render? who knows, that's up to you.
just play with the layers, setting them up in different opacities or different properties.
keep at it.
