Firstly congratulations on this as I've had no luck putting this model together.
Ok you asked for coments so here goes:
The pictures are a little bit too small to make out any read detail and in addition they are a little grainy as well, however the second picture of the group does show that applied some careful attention to the teeth and mouth area.
I'm not sure if the Orange/Red scales are as strongly defined as they could be but that could just be the photo. One thing I would suggest is that you could carefully wash in the areas around the eyes and start of the crestial ridges witha darker colour. This would increase the contrast and place more emphasis on the eyes and front of the model. (Can't really call this a mini.:) )
The basing effect really does look good and very much like a jungle area that the Carnosaur os bursting out from. Thanks for sharing. :)
