Great tribute art!
I really enjoyed the film and found the personality of the characters to be very refreshing, too. Your image really captures the overall style well, and it would have been cool to see it animated in a traditional way...though the CG was phenomenal.
My only complaint here is regarding Pascal. He doesn't appear to be actually looking at Finn. It might have worked better if you had drawn his lower lids rather than the upper ones, and then had his eyes looking up and left towards Finn's eyes. Like this Pascal just kind of looks bored or annoyed rather than suspicious. His head also looks a tad too angular.
Finn and Rapunzel look essentially spot on to me. The forest background is nice and totally unobtrusive, and the subtle blue highlights add a really nice touch. Great work!
