I know I’m usually picky and I always things like “yeah, your work is good but…” … and even though you yourself say that there are things that can be improved… Well… I first had a glance, and thought “looks pretty good”, which is the common process. Oh, I should mention that I clicked this thread mainly because I saw your name on it… Then I proceeded to further inspect the images. I zoomed in… and when normally I start to flinch seeing some things not so apparent at first sight, in your render I was simply mind blown by the amount of detail… The amount of work… For some reason, every time I see a render, or painting, photo, sketch, etc… I instantly classify it in to “normal”, which would b something I consider myself able to do, and “professional looking”… So, although it isn’t perfect and I think I see those little details that you say can be improved, this would still belong to the latter category, imo.
Wish ya a nice 2 weeks of vacation (guessing its vacation?)!
