Caldera Sunrise Sounds a Bit too Much Like a Beverage...

I've started trying out doing environments a little more. After taking a look at a few quick albeit not altogether helpful video tutorials I get the basics of it a little more than I did before. That said, this isn't my proudest moment. This drawing took about an hour and a half or an hour and three-quarters.

Also, true to my name I will be starting a series of drawings involving dragons very soon. This is the first of them. Anyway, here's some kind of Caldera environment at dawn or dusk. I really need to work on skies at some point...
