Wow!

This is awesome!
I have to say Tornetar looks much scarier in this version (though he doesn’t have that fantastic drool

). His glowing eyes and the reddish area around his mouth make him look very menacing, and I like it that we can see the detail of his spikes and armor.
Grandpa Longneck looks good too, but his outline looks kind of strange for some reason, and his colors seem a little off (his spinal ridge doesn’t look dark enough compared to his body color, and his underside looks too blue). To me it also seems harder to fully appreciate some of the detail on him, namely in his face.
The colors in this version look excellent. In addition to Tornetar’s color palette, I love the colors of the ground and the sky.

That said, it looks like Nathair miscolored the area in front of Tornetar’s ankle (The line in front of it was actually an erased line, but it looks like he thought it was part of the outline of a rock or something). He also missed filling in the background color in two spots between Tornetar’s hand claws, and another little triangle of background between Tornetar’s stomach, leg, and tail. Finally, I think those other eraser marks should probably have been colored over or otherwise removed. (Do you have Photoshop or any other program that would enable you to edit scanned pictures and get rid of eraser marks?)
