Some new head art here:

From Top to Bottom:

Brontosuchus: A close-up from my last full body design, but with a new design for the scutes/spikes. Brontosuchus's head is more like a Alligator's head (U-Shape) than a crocodiles (V shape) (yes, I am aware of Caimens and Mugger Crocodiles), but with the two arrangement of the later.

I try to make a new arrangement of the spikes/scutes. There is five rows with second spikes being huge. I think it looks good, myself.

Gezion (Below): Close-up of Gezion's last design. I changed the armor plates a bit, a singular tall spikes with smaller raised plates on the sides. I believe this looks better than the original's more singular raised plates.

The head looks a bit like Zilla's, but I wanted it to look a bit bulky, and the scales on the chin are pointed forward (similar to the shovel-chin idea, but not as silly). The placement of the legs is more based on the Ajote (Mole Lizard). That reptile's Spanish name is "Lizard with Big Ears).

Monsturra (Left): This is a improvement from the last face design. The head is more based on a Tyrannosaurus than a wolf. Yes, the three rows of spikes/scutes are back. Was influenced by Neo Jirass with that design.

Center:

Apollosaurex (Left): He basically stays the same. There are two small tusks on the upper beak. Just looks good there. Looks nice overall.

Omegaken (Right): No big changes, just felt like drawing this monster.

Deinopteryx (Left, Below Apollosaurex): Tried to give him a less "chicken" look. Doesn't look bad here. The hair looks very good here, I must add. I thought it looks better than that wrinkled skin on my last drawings.

Monsturra X-TREME (Right, below Omegaken): Gave him a wolf-like snout (this is intentional) Not bad, compare it to the real/normal Monsturra.

Bottom:
Vulgar (Left): Tried to give him Monsturra's T-Rex snout, but give it a deformed feeling. I like parts of this design (the swollen lower jaw looks good), but other part is rather "eh". Overall, not a bad idea.

Ramuzile (Right): I used the last design, but added more detail to the warts, and yes, the eyes are frog-like.

So, what do you guys think?
