Please comment. It's the only way i can improve

I would say lose the white lines, or lower the opacity as they stand out too much, Instead try and maybe add some different effects behind him, using textures or brushes.

hmmm.

Not the best bg mate try to work on it more. Render is to up in my eyes maybe to big or you should blend it in more. texture work aint the best it could be better. text is fine.

kiu mate have a look at the tut section you will get heaps better
