Cool Piece John! Thanks for posting.
You really nailed the pumpkin and the fire looks great. I'd suggest some reworking of what is under him. Is it supposed to be clothing on a body or a dirt hill? Right now it's tough to tell. If its a body, really focus on using harder edges and simplifying the shadows. Right now they are very rounded and don't look natural. I'd put a dark coat on him and then lighten those trees to the left. That makes it easy to paint and not get lost in the fabric.
If it's a cliff or a hill, just use way less soft edges and make the shapes more definite.
All in all a great piece!
