I like the atmosphere in this one very much, well done. 
I like this a lot, but I think the purple parts of the monster recede too quickly, and seem disconnected. maybe try to work some of the warmer colors in there for continuity?
Awesome! The monster being the light source for the whole piece gives a great atmosphere!
The tiny characters are expressive and fun, even at such size and all over the piece you did the detail work! (cobbles, roofs)
That together with an original monster that is fun to look at! I just think that his right leg is not visible enough.. A bit more red in there? Same goes for his back..
Is this just a mockup or is this for an actual game? (*hopes that all this stuff is animated ;)*)
Hmm "Kirin" seems to be different according to general mythology - more like a unicorn horse thingy, not so much dragawn.
This one is odd - thought it attempts an extreme perspective with significant foreshortening it feels very flat.
Favorite part is the architecture.
