Holy hell. That's two news in around six hours. First, this is the first time I've really considered atmosphere while colouring, instead of just slapping it on later. Second, O MEH GAWSH IS THAT A BACKGROUND THAR? The amount of red in this made me see a bit funny for a little bit, too. Also, the smoke brush in PS Element's Pen Pressure brushes is really good for watercolour-y effects. Too bad you CS users don't have it, HAHAHA. [gloats]
And yes, sand can be black. Go to Montserrat or Mauna Loa. It's because of the volcanoes.
Yes, in my world Satan is a girl. A very hyperactive doofy girl. So is the equivalent of God, too. And her name is Sacralita, only she's got a bit more sense and is generally more tolerable. And they're twin sisters. Like the song. And Hell isn't that bad, either. Like Greece.
Feel free to pull a TL;DR. I just was feeling wordy.
Nice! I'm loving the black sand! *loves rocks and things of that nature* When it comes to the Hawaiian Islands, I don't know which I love more--the black sand, or the green sand. They're both so purrrrrrty... X3
I...don't understand the art-related stuff you're talking about. *is not an artist and has no knowledge of the tools of the trade D:*
All-in-all, I like it! Very nice. And the colors are pretty, too. ^_^
