Wow! I don't know if I need to say more really... but I will! ;) This image is amazing, not only does it look like the animated movie, it brings it to the next level with the obvious jade weapon that was common in that age. Next, we've seen Poh(?) have that helmet/hat in the series but here it is part of his outfit. The fact that he is practicing against the SKY shows that he's reached the level of master (level 99). Master Ugwey (?) would be proud ;)
Execution wise, as I said, the rendering looks like the movie almost. The pose, layout of the piece, colors, etc. are all top-notch. If I didn't know better I'd say this is a randering for a poster for Kung-Fu Panda 4! Amazing work!
