For the robot what i did was make 5 layers of the robot and smudged them with a grunge brush. I then set the layer mode on the second to dodge, the third one was set to screen, the forth layer was kept unchanged and the last one (#5) was set at light only and i gave it a Gaussian blur of 8-horizontal. and 10-vertical. Forgive any errors I'm new to this so the terminology is new. Anything else that could be improved on it?
Yes I believe I did, It's just a matter of finding what suits the picture so lots of trial and error for me.
I love the background but not the render... and change the size of the texte (smaller) and change the color and change the font.
