Something that stands out to me is the reaction Donkey Kong has to Diddy pointing out a banana while DK already has a banana in hand. I don't know if you intended any meaning behind that but to me it shows a certain added level of manic in DK's character and I love how that shines through to me in the style and expressions of the characters as well as the little details you've thrown in. Awesome piece Dirk.
Lol, my brother only just yesterday bought Donkey Kong Country Returns - Tropical Freeze yesterday and we're bother eager to play it (after having such a blast in the previous DKC Returns game) But we swore to finish 100%-ing everything in Super Mario 3D World first before we touch it
I love Diddy Kong's facial expression, it's as if he really is making that "Oooo-Ooooh!" noise that monkey's do
