Its great how you have variety in your work, taking things in a wide perspective is surely a challenge and you seem to be kicking his ass. I'll check out the alchemy though looks very interesting. Also when doing figures its important to take your time, one minute studies in my opinion are best for rhythm and form. Liking the cave painting alot, the greens definitely set the mood. But, be very careful when using the airbrush it easily ruins solid forms and structure. Don't get caught in its illusion of aesthetics.
Keep it up!
