A wereshark huh? I do admire the details you putter in here. Including the teeth (teeth are annoying for me to do sometimes. XD I need to practice different mouth styles). Just curious about one thing. Is he walking on water, sea level, or land?
Actually, i think the background is okay. but sometimes, when the background is colorless, it can confuse a little. For example, there's this one time before I joined DA, I though of drawing a wave of vanilla and strawberry. Though because there was no colors, people though it was the beach. So the background looks okay. But there is always room for improvement.
