Whew. It's pretty late... 1:44 PM, as I'm writing this.
Touch. It's a powerful thing... more powerful than most people realize.
L ot of experimentation here... I decided to go with a fairly smooth and undetailed nebula... could've textured it more, but I think it's better this way, for this piece. I actually used an... interesting texture in the nebula, all over the place.
In order to get the effects I wanted on the planet and moon I had to merge the layers in their respective sets, so don't expect those to change. Working resolution was 8000x6000. Why? I was too lazy to resize the big planet (originally approximately 4500x4500 px). Actually, to be completely honest, the moon uses the same texture as the planet, without any color layers on it. I admit it.
Some detail was probably lost resizing it so far down, but whatever... I guess you can request a print if you really want to see full detail, ay?
Thanks for all the tips people have given me... each comment is invaluable to my progress.
Full view dammit, I put to much into this to not have it fullviewed.
