Creepy Cave Of Mystery!

Here's a new background I painted this week for fun where I tried to play with the environmental elements a bit more to create a sense of mystery while having a touch of realism to ground it. I like doing caves (and other outdoor scenes) as they're organic and easier to paint than doing a city which is built with exact lines and perspective. These have perspective as well, it's just looser in terms of depth as I like to work with foreground, middle ground and background. The cave hole in the center is a separate piece so I could pop it out and put another background there if I wanted it to have more depth. Like if I added a city scene in the hole to show we were nearing the cave entrance. I do like the color theory for it and it has a nice warm feeling to it. Kind of like autumn fall season in mid October as the leaves are falling off the trees.
