I agree with RicePirate...
Great work... there is only one flaw that I noticed that kind of bugged me. To me, the way Lincoln is standing on the dinosaur is a tad false. I think there should be a bit of 'squishy skin' where he is stood to show the pressure?
Also, aybe put the foot ON the horn, so it makes him in a decent posistion to shoot. Shooting with one leg cocked just seems weird to me.. but hey... you have great talent!
Funny actually, I was making a game about Abe Lincoln recently :O - http://188.8.131.52/labs/ABE/
