Just some random guy (or girl) in a fursuit. Imagination vs reality. Sometimes it looks really weird if the fursona is slim, muscular and so on and then you see the overweight fursuiter shambling around. O_o
No offense here, I might not have the overweight problem, but I often think it looks kinda awkward when I move in a fursuit. When I get my own someday, I will certainly practice in front of a mirror first. See where the problems are, like what moves I should avoid so that there'd be no "bald" spots.
