One-a-Day #2

Recently I finished reading "The Princess of Mars" and was really taken with the imagery (and all those Frazetta drawings now make a LOT of sense!). I tried to come up with a different idea for a creature with 2 sets of arms and I stumbled upon a concept of one set of powerful arms for fighting and heavy lifting and a second set of arms for delicate work like writing or eating. So here are some visual ideas:

The sketch posted earlier has the same idea, but being an early try at it, is not very clear (the folded arms look like some sort of weird abs)
