Feedback from people who know what they are doing would be helpful in getting better, but I do not know a great place to ask for that feedback.
No BSE is not for Critiques. (See point six What questions should be definitely off-topic?) Any question like you described would get closed as off topic.
You could try in our chat room there is almost always somebody there, but I dont know how much help you will get.
A much better place for feedback is on blender artists. There is a entire thread for Focused Critiques.
Try CG Stack Extchange, I guess that would be the right place to do so, since I've seen a post there requesting feedback, and nobody seems to object: https://computergraphics.stackexchange.com/
Still make sure to ask the right question, as in asking, what do you think is missing? Or should I do it this way? Rather than How do you like it?
