Neat

Ok this one here is neat and different. I do think you need work with anatomy of you are going to be adding arms to a basic human shape. The blue hair and skin are colored and drawn out very well. I would like to see more of a background from you instead of just black. Maybe some effects around her arms like casting a spell. This is neat overall And really liked what you did with this one, so keep that kind of work going strong. So I was pretty pleased with this you have outdone yourself, on this and this one has all the great elements in the right places, you do good work. maybe adding a Twist here and there would give it a more unique feel and look, but might be nice with some extra changes.

~~THINGS TO IMPROVE ON~~
Take a look at other 4 armed creatures anatomy and how to place the arms in a morw fluid way. Also get a nice background in there with effects.
