my only critique would be that the colours are too overwhelming and saturated (speaking of all the related pages in your gallery). i would desaturate the background a bit just so the characters shand out and to allow the eyes a bit of a resting place when looking at the pages. it would also help creat depth of field which is missing; everything looks like it's on one level (i.e. lacking background and foreground). this i think is most notable on the dinosaur as you can't really distinguise where the head starts and the body begins, you have to look hard at the linework to figure it out whereas the colouring should make the distinction.
I must say though that the colourist has great technique and style. You guys are doing a good job.
