Thanks PDNNOOB for the suggestions. It's kinda cool to be told by an expert on the subject that my first planet is almost flawless. (Yes I did use 3d render...good eye)I will try lens next time.
I know the starfeild sucks, it was actually a small part of a bigger starfield I did (my first), but it sucked, the clone tool did some weird lines and it didn't show up until I merged the layers, so I cropped it all out and used it to show off my planet. can be seen here
I will try your suggestions on the starfield. What I did was made a black background, started a new layer, made it black, created noise, then adjusted brightness and contrast to thin out the stars, set layer mode to screen. Duplicated the layer,then adjusted brightness and contrast again, and played with levels, then rotated the layer 180, set layer to screen, and then erased here and there on both layers. I then flattened the layers and cloned some areas. I also added another layer and I think I did, render sparkles.
Since I posted my planet I have made a new starfield, I'm fairly happy with the results but being new to the whole spacescape thing I would like some expert critique on it.....be brutal.
