Not too sure about the wings to be honest.

There very small so they wouldent be able to do much in a real creature and make it look cartooney, which by the looks of the rest of the model your not really going after.

Thats my 2 cents, but its up to you.

If it was me I wouls start to work on your main character and leave the monster at the moment, as the main guys going to have more focus in the end produc, as he's the hero.
