At first glance, it looks like a great drawing! But upon further inspection, a lot of areas like the pants, shoes, arms, fur, and hair are quite under-detailed and undefined which hurts the final drawing. I understand that this was an art trade and just for fun, but I feel like you could work on this. The torso has some good detail, however. It's just that the rest of the drawing needs that level of detail! Still a solid drawing overall.
