Really nice! I'd have removed the tacky windows movie maker title screen, it looks very unproffesional and gave me low expectations for what turned out to be a nice animation. I liked the poem and the reading was great, loved the guys voice. Unfortunately I don't know spanish so I appreciated the translation in the description, subtitles might have been better though.
The animation is self was decent, the frame rate was a little low but I appreciate traditional animation is a lot of work. Loved the transition at 0:23. Character design was really cool too, and that shot of the mountatin at 0:45 is perfect, loved how it moved. The shot at 0:52 felt far too static, could have had some background drifting by to show the birds speed. The transition to digital animation was nicely done and I liked how you used photographs.
All in all an original and engaging work! Great imagery, appealing character design, intriguing concept!
