Thanks for the input Ace Dragon. The images are actually rendered at high res (ex. 6000x3375pix for the Ab Infinitum) but I scale them down before uploading here. You’re right about the cosmic dice; I try to bring the time it takes to build a daily from about four to one or two hours. It appears that most of the time is spend to fine tune the scene/composition and do test renders. Rendering the final image at high res also takes from 2 to 6 hours when using cycles. Since I render big images I will upload them at a higher res in the future.
An amazing visual here, though I digress on one thing.
Your images tend to have a lot of repeating elements and symmetry. While this may be a good thing for a lot of images, a little variation and a touch of asymmetry can go a long way in enhancing things.
Also experiment with different background styles and backdrops, the same white or bright colored backgrounds can start to get old after a while.
