I love your use of colours in the elf piece! The red makes it pop nicely (:
Since the red color attracts the viewer's eyes because of the contrast, you might want to rethink making his shoes red since the focal point (as far as I've noticed) is his face. It pulls you out of the flow of the overall design.
I've looked at your Artwar piece as well and dang, those shapes are hella neat, good job on that!
