Looks great! Pokemon and The Lion King--two of my childhood favorites in one picture! :-D. I like how you did the clouds, and how you hid a Dragonair in there. I also see a profile view of Blaziken on the far left--at least, it looks like one to me... I also like how you drew the swirling flames in Rapidash's mane in the bottom right corner. Arcanine looks so proud and majestic. He truly is the Legendary Pokemon!
Isn't it based off of a canine too ? Probably the same with the Legendary Beast trio, where the Pokemon appearance origins are based off of mixture of animals like canines & felines, also mythological creatures.
This is pure amazing, love what you did here. The coloring looks awesome.
