Hippo Ice Skating rough sketch?

So originally I was going to draw a hippo roller skating (you can kinda see wheels), but I wanted to add something else to the hippo, either a jacket or scarf.  I decided to add the scarf and thought it would be better then to have the hippo in ice skates!  I did this sketch rather quick so I didn't add details to the ice skates, plus I need to find a picture of ice skates online that I can draw from!  What do you think?
