Concepts were made by my friend and I just tried to flesh them out as much as my meager skills can allow. I didn't go into details since this is going to be shrunk to fit into a word document.
The first one is supposed to be a knight travelling or entering a dark catacomb.
The second image is that of a necromancer casting a spell on enemy spear men while his undead approaches from the forest. It's hard to understand I guess. lolz.
If I could have 1/20th of Craig Mullin's sketching ability I'd be an impressionist master. lolz. For now though, this will have to do.
