Treat or Trick?

because I'm bored I'll try criticizing this //shot

Negative:
+The two pieces seem to be lacking in unity ^^" Like where the right arm and pumpkin are chopped off by the divider, it might have looked better if you continued the pumpkin to the other side (while giving it a much meaner look than the cute treat side) and if the left hand on the treat side isn't drawn-- so that people can see that it's one drawing.
+The moon could use some help, try sketching its shape first?
+The tail on the trick side could use more shading hahahaha
+The blood looks more to crayon smudge than blood. I think because it's lacking the "liquid" property, but the color is too bright to be considered dried blood. For this kind of thing, I really suggest looking up for some preferences
+The left wrist on the left side seems to be broken...?

Positive
+I really REALLY love the color scheme! <3 Blue and Orange makes for a very good contrast and you've executed it very well in this piece. Just lovable.
+The pumpkin bag is simply irresistible.
+I simply adore the simple background. it really fits with the theme!
