Here's some quick sketches I did a while ago to test my drawing speed as well as my ability to come up with for new characters.

This mouth-within-a-mouth creature is a homage to Giger's Alien and the Predator. The bladed tail, armour scales and six legs adds to the menace.

This creature is probably inspired by some religious relic I guess.

Since all orcs look similar one way or another I'll just let him carry a burden for differentiation sake.

This is my rendition of a telepathic sorcerer from some planet. The feelers on his forehead says it all.
