Hope this is of some help.
Some of the colours seem a bit strong for me.
I feel there is no particular "point of entry" for the eye into the image or a circularity of eye flow which takes you around the imagerey and back to the entrance point. (Does that make sense?)
Part of this is contributed to by the similarity of size of the objects but also by the llimited variations in the objects colour differences?
Red/yellow  colours always looks as though they are at the front, so things that are further away should be less red/yellow?
Having been that critical, your drawing/modelling is, really ,very good.
