uhmm…how can i say… :o …This trex kick some ass!!! I love your work man…The guy like you give me inspiration! Nice job!
Very cool, Nayman!
I am also working on a T-Rex. Although I don’t believe my head has that much detail. I’m hoping to use some nice detailed textures.

Natron, you sure the tail on your t-rex is long enough? In that pose, it looks like he’s about to fall over from lack of counterbalance… other than that, they’re both very good.

Very good, Nayman,
your head is very nice, nostril has a strange ridge, IMHO.
Sorry, Natron, Can’t see your page.

great looking! theres just something, a lil something about the bottom jaw that doesnt look quite rex-ish…no im not just thinking about the teeth either 
i think the front end is a lil odd, oh but i dunno! hehe i avent seen a rex since the last time i sw juarassic park… models looking very detailed, great job
i agree with granpaboy, the lower jaw looks funny. behind the nostril area, where the upper lip starts to bulge/jut/curve downward, the lower jaw needs more vertical mass, to follow the upper lip. otherwise, the bone there will be prone to breakage
