Excellently done! I remember watching parts of this coming together a long time ago (especially with the Slime Pit) and am glad to see it done (or 99%...are the Imps and droppings all you have to add?). The Beast Monster (the puppet) looks just like he did in the A He-Man and She-Ra Christmas Special (love the extra rows of teeth addition!), and all your characters--both custom and MOTUC--all fit in wonderfully well!
Oh, btw, I have an extra IMP. If interested, PM me for details.
