Excellent in both, concept and execution. my favorite in this challenge series.

Se ven geniales. Felicitaciones!

Magnific job on the fire-thing animation. It looks really magical and alive.

Cool concept, and pretty badass looking too.
I think, however, that, either the lighter shades on the helmet should be extended a bit on the body parts, or the helmet darkened like the body, since there's a strong contrast between the two, making the body look less tridimensional than the helmet.
Well.. that's assuming all the parts are made on the same metal. If the body is made of a more matte material than the helmet, then forget everything I've said.
Other than that, It's really a good piece, and very expressive for a character not showing their face. I'd love to see more like this.

Great choice of colors for a retro vibe, and very smooth for this few colors. I love it.

So lovely even lava is trying to move carefully, trying not to disturb the sleepy one, lol.
I think a subtle variation in width from time to time on the background lava streams could improve them a bit, since from the viewer's perspective, it would be difficult to understand what they are without the general enviroment and the foreground stream as a reference. On the other hand, the way they are right now also contributes with the quiet atmosphere.
Nonetheless, is really a calm-inspiring, lovely work.

This is really well done! I don't understand why you don't get more faves on this one.
The only detail I see, is that the light over the left forearm (at the right of the picture), being too straight and sharpened, makes it looks a bit solid. Also, it could've been a bit shorter, considering the shade casted by the upper arm.
The character expression, on the other hand, is particularily good. congrats.

I love the atmosphere in this one, and how distinct and expressive the characters are with such little details.

Just for the sake of nitpicking, however, I have to say that the continuation of the tombstone lighter shade over the upper wolf's nose, makes it look like the tombstone's shape it's missing a chunk on top at first glance, so I had to look more in detail to confirm it was actually a tombstone.
I think letting the wolf merge with it's shape, or at least, reducing the outline width by one pixel on the wolf nose could've aided more with the immediate dfferentiation of both shapes.

Everything else is great to my eyes; I faved this for a reason.

Nice! I've never seen this rhombus-like shading before, and you did a great job with it.

To me this kinda feels like: H.R. Giger meets the rot colouring of Sladislaw Beksinski, and the gooey, wavy backgrounds of earthworm Jim, and somehow the result is awesome. 

Thanks, SeDiceBisonte.

Yeah, I got kinda hooked with this one, and ended up adding more details than originally intended.

This is crazy in the good way. Congrats

Magnific Texuring, indeed. 

This is great, distinct, and truly gives a dark fairy tale vibe.

However, I would've added a bit more foliage between the animal and the tree over its head, or move one of the two a couple pixels sideways, since the tree is lining up with the animal ear, making the distiction a little difficult at first glance. 

That's just nitpicking, tough. Everything else is really good.

Absolute Masterpiece. 

Amazing! The only reason I'm not faving this it's becouse this yellow color incinerates my eyeballs, but you made the best of it, for sure. 

great work with the lighting!

very good! congrats!

I love the old classic painting vibe on this one. amazing.

Definitively agree with the album cover or poster idea. well done!

This is impresive! Congrats.

Impressive.  You've somehow managed to make a piece with such strong contrast to go easy on the eyes.
I love the ambience too.

This is great! and very psychedelic
 

wow, amazing ambience.

Thanks, digitalCoffin!
