Haha, I -love- this character. You didn't go for the typical big, burley, top-heavy guard, but instead went for a grumpy old man.Perhaps it might be best to flatten the feet like clown shoes, but angle them into a sharp point to go with the rest of the character. Currently, the large, bulbous shape seems out of place.
Funnily enough I did feel that was letting the character down. I have made them a little narrower in my storyboard.
