Nice reel! Love the take on Mario. A bit long and slow at points.
I'd like to see some additional notes during the wireframes about what material layers were used (normal map, spec color map, texture resolutions, etc.).
I don't see the need for two whole rotations around the Hercules model, just one will do before you show the wireframe. The L for "ow res" is getting cut off. I'm not sure why there's a LOD for the dog, but not for the man, and why we never see it.
The Gypsy is a cool piece. Is this designed to be real-time? If so, it'd be nice to overlay some specs.
OK, I'm going to be blunt here, you can thank me later. I'd nix all the figure drawings. Sure it shows you can draw OK, but they aren't knock-out good, and if you're going for a games job none of us who are hiring artists care about figure drawings. Even if it's the only art you have, I don't want to see it, it's just a waste of my time. Remember the people reviewing your work are impatient, they have ten million other things to do, do whatever you can to shorten your reel and not waste their time. They're not applicable anyhow when you're already showing concept art.
I personally don't like thumbnails that are tiny croppings of the artwork, but I can see why people want to do this. It doesn't help when you're going through the art and want to get back to something you saw before, but they're all cropped so it's hard to find that piece you liked. I'd also like to see the thumbs be larger.
You could really reduce reduce reduce. Too many items, I just don't have the time to click on all those thumbnails. Only the best of the best should be here. You should make up your mind what the purpose of the site is (getting a job, or showing your art to your family/friends) and if it's getting a job, what position? Concept artist at a game dev? Be relentless.
Nice reel, the only reason I'm spending all this time is because you show a lot of promise. But the site is preventing me from seeing your best work.
