So I'm literally completely new at photoshop, don't really get it.

I really need someone to make me a poster of some kind for my YouTube Channel.

All I want is a cool background with the name "PotterMoreFan" written in the middle somewhere.
I'd love if somebody could make it all by themselves and post it.
If the colours could be light in the background and a bit darker for the text.
Thank you for reading.

Need a bit more ideas.....size, colors....theme?

Umm, blueish theme would do good.

I'm really not sure, surprise me =]

Big writing in the middle, and say clouds or something in the background. Anything professional looking really.
I'd be willing to showcase some of your other work on my channel if you want.
