Nice piece. I like the concept. You did a nice job with the details.
I noticed you requested a "constructive critique." We're trying to organize a live crit meetup on July 7th if you're interested in joining. Details are in the discord channel (which is linked from the Forums at the top)
I noticed the lines get a little crooked off to the left a bit - but over all this looks very much cleanly done. The blocks and variety of shapes / sizes really make this image more dynamic, and all, as well. The only thing about it is, as much as it's eye catching and draws you in - there doesn't seem to be any one place where viewer can focus for long and i just want to say well done on that. Especially upon reading your description that went along with it.
This is really cool. I don't think I can really offer critique as it's so different from any kind of art I have experience in making, but I like the piece, and the little "cores" or kind of eye-like spheres you have inside some of the up-close blocks is really neat.
