Mythology themed Sketches

First, I made a spitpaint of medusa's death. 

With a similar color scheme in mind, I later used "Medusa's Death" as a starting point (canvas) for the cyclops who went on a rampage shortly after losing his sheep.

 Later, I had an idea completely with a color scheme completely different from the previous two.

These were all 30 mins. I'm really tempted to push some these sketches further.
