nice sig Sin! vast improvement from when you started your app.
-the scythe seems to be in front of the reaper, when in fact it should be behind and therefore blended to show that.
-not feeling the blue flame at the bottom. had you chosen a cloud render or some fog/smoke would be better.
-the cloud brush needs to go as well. again, try to find a cloud render to use instead
-to create some depth with the blue orbs, smart sharpen that layer, then use a 15% blur tool over each one individually varying the amount of blur to show that some are in front and behind the render.
