Wow, Sue, that is quite a neat extraction. If you had not said anything about having drawn the branch, i would not have guessed you did it. I like the little details you added, like the lifted corner. Due to the yellow of the paper and the white of the owl, i might suggest adding a “reverse” shadow (something faint in the opposite of what the normal shadows are), just so it makes some differentiation between the two colors. It is a little trick i use when colors tend to be similar in an area where there is no shadow.
One sure thing, you did a great job of extracting that owl!
