Very neat concept, toonleap. This definitely looks nice, but there are a couple flaws I would have to instantly point out after looking close up to it.
First, the extraction is alright. Nothing high off the end and nothing slightly remarkable.
The mist also have lines separating it [not sure if this was your main intention] and it does kind of ruin that visual appeal once in a while.
Also, the moon seems a little too edgy on the top. Why is it all bumpynear the top?
In any case - the positives:
The scan looks great and the variety of colors seem to blend in well from place to place. It definitely looks colorful indeed. The sky looks kind of inviting around the top edge of the wallpaper - I'm not sure of the rest, but most likely, I love the scan overall. Her eyes are so beautiful, I'll have to admit.
Other than that, the wallpaper is so-so in my opinion - not too shabby, but it is in definitely need of improvements. Keep it up, toonleap!
