This Pokémon is Keldeo! This is its Resolute Form. I was inspired by the new movie to draw this. I used the pencil tool on low opacity for everything except some faint frosty breath, which I used airbrush, and a couple "frosty" spots on the ground using the dodge tool. This took me around an hour and forty minutes. I really like it.
I drew this on Bulagarden Oekaki.
