Goto effects<all renders are there.

I now have photoshop. But ATM people need to send me a picture of themselves in order of me to make an avatar.

I dont know nothing about photoshop so I cant help you
if you were using gimp I would tell you some tricks

You really need to work on effects, backgrounds and better design. I'd say this is a good start for a beginner at gimp.

TIP: Try type in-game these commands: /opt hud /opt uke.
And, try to wait until the "win caption" is gone pressing P
And shaders would help you.
