Sweeeeeet. I really like that head design on the creature. It's fun and unique; I wish the rest of the form had the same novelty to it. Maybe play with the claw and foot sizes, add some of that texture on the head to the rest of the lower spine. I really want to see this design come alive so keep going! So far so good.
Cool design! I don't think I would like to run into him while out galavanting around in the desert!The first thing I noticed was the glow that is coming off of his face. It almost reads as some sort of bioluminescent glow or being highly reflective. I don't know if the bone-like material that his spikes seem to be made out of would have that effect. If you are trying to draw attention to it, I think that you have a strong enough value system to keep the viewer's eye focused there first without needing it.
Kylie! This is super cool! I was like dang, sickkk. I really like the colors you have goingOn with this and the double eyes look awesome. It has a unique alien look but also like an old school look, don't know if I am making sense but nicely done. I agree with Ethan. Maybe lower the glowing effect on the head. I think your values are working well with the focus on his head without the glow.
This one is gnarly, I love it. The only thing that seems weird are the blurred smudges on his back legs; they look like gausain blur spots.
Cooooool! I love those spider eyes, very nice :D I think the back legs/haunches area looks a little small to support the front end, but I think you could fix that by just making the feet a little bigger to balance it out :)
This guy is pretty cool - I like it. I think anything I would have said has already been mentioned. However, one thing I think you could try out would be to take those bony spikes coming from his spine and kind of repeat them a little bit down his limbs and torso - kind of like an armor, but much more subtle. I can already see it happening a little by his neck and deltoid. Try it out if you're feeling adventurous!
