Heh, you can tell you went off to play Hansel and Gretel and immediately after was like I'M GONNA DRAW SOMETHING. From what I understand, the audience's perspective is such that they're viewing the town of Onomatopeoia -btw intriguing name choice, may I ask how this came about?- from the side or angle, yet they can peer inside and see the inner workings. Groovy concept. The architecture of the place seems to be less realism focused and borderline abstract. You and your birds :P I believe you should properly give a name to these half bird, half human character race you are so adamantly infatuated with!
Clearly you feel strongly about environmentalism, seeing as you seemingly transformed the inside of the buildings into nature's proper living quarters. The bottom half seems busy, while the top half has nothing to catch the eye though. I'd prefer consistency in terms of activity throughout and simply MORE going on. Complexity in cityscapes (apologies if this isn't the direction you wanted, it's hard to read people sometimes) is a positive thing! Give the viewer so much to absorb it takes them many minutes to realize everything that is going on. Expand and show us the depths of your creativity, I hereby CHALLENGE you to show us more of this world. You've peaked my interest, but left me unsatisfied.
I have one word for you,
You are brimming with it, you just need somebody to bounce ideas back and forth with. (Not myself, somebody you are closer to on a personal level) You need somebody to inspire and pull the best out of you. In short, I think you're someone special and I wish I COULD test your limits and help make progress, exploring different artistic avenues, but this isn't exactly my most familiar of subjects.
Kinda danced way off base it seems... anyway I enjoyed this a lot and hope to see more from you. You seem to be bringing something new to the table each time and that's encouraging, gives me something to look forward to when I check my feed.
Awaken your desires, never stop chasing.
