El mariachi, (My second animation)

I sent this post two times, I dont know how to delete it, sorry my bad.

Hello, I would appreciate if you can critique my animation, its a silly thing but I tried on purpose to do something outside my comfort zone. It took a lot longer than I thought it would (3 to 4 weeks) The glitches with the grass are my fault, I rendered everything on 3 computers and missed the particles cache on some frames.

Thanks! Best regards!
