Wise one
Goblin Kamikaze
Alien egg
Eagle Warrior (I worked for a couple of hours after the deadline on this one)
Sand People
Bank robber in the vault
Catapult assault
Wind temple
Desert Trek
Princess saviour
All done in 30 mins, without reference or photo texture. The last one (Princess saviour) was all done with one brush.
I really like this exercise as it forces you to go straight to the point.
