It's a very cute way of mapping it. Lizard heads go! I've never really seen that kind of mapping, but it's looking good. As always, vector feels clean. The only issue I have is that the bottom area is looking empty.

My own work:

I likes, although... you could blur a litle the left arm and the bottom of the torso, else it's too outstanding and my eyes are confused where to actually lookand maybe add some dodge/burn effects on the visor and the under part of the helmet

Doxxy, makes me want to play skyrim. Fix the mouth to make it more mouth like. the black line isn't expressing it well.
Raid your text always stands out too much for me. Any way you can blend it a bit?

Yeah, Raiden, soften the edges of your text a bit so it fades very slightly into the background.

Since when do you art. But I realllly like that smoke coming out of his eyes/mouth. (Is it fire? If so I think it needs more highlights) but yeah that is pretty nice.

Eyes could be bigger imo

i don't usually do art, i just had to make one when i saw the deadline of that event.
and yeah that's fire.

i think it's fine how it looks now, i won't increase it's size.

On the topic of heads, who do you think will win the Texturemaking Challenge Thingo?

It's already finished and maldred(or something) won.
