Nice drawing, and good luck in the future with other designs. The castle seems weird though, its supposed to be behind the characters I belive, but it kind of looks like it is right next to the characters and one's head is looking right in front of him (like 90 degrees) and sees it. It looks in the background because their heads are almost bigger then the castles top, like an obstical illusion. Anyways good though
Thumbs Up.
