I think you made a lovely rendition of Jagatai Khan but I have a little nitpick (even though I could never create something like this...) You've done him in a toad angle, i.e. looking upwards towards him, but the background is obviously made looking down on houses and a plain. The combined effect looks either like he is bending backwards or that the ground is bending forwards/upwards like a wave about to fall over him (There's definitely something strange with the angles on the house roof and the house).
If I were you I would skip the houses, asian though they may be and instead go with open blue skies and perhaps just a tree or something to enforce the plains perspective. But hey, it's your masterpiece, and masterpiece it is :tu:
