any-anyways, please share moar thoughts! I would like to ask an important question though: How do I make my background mountains more... mountainy? Actually, im not too sure how to do rockiness in general, in the foreground the grey-er parts are supposed to be rocky, but.. that just doesn't feel... detailed enough?
Not sure about the background, but with computer graphics there's the bonus of being able to add textures to a piece using pre-existing images. For example, photoshopping images of a crocodile's scaly back onto concept art of a dragon, to help suggest the texturing of the dragon's scales without having to spend tons of time detailing each scale. It's common in the concept art business when pieces have to be done in a quick time.
There's references for the technique online, and I'd imagine for multiple programs. It uses layers and transparency and magic stuff like that.
I'd probably recommend adding "rocky" textures to the closer rock formations and then suggesting the background has the same detail...by, uh...adding similar detailing to it by hand. I don't recall the term for it, but it's to imply the back rock has as much texture as the closer rocks, but the detail just can't be seen due to the background being further away. hope this helps a bit.
