Nice work m8, but I wouldn't like too say much about the walk cycle, other than it is definitely robotic. Delve into the 'Animators Survival Kit' to get a few tips!
Eggprops did indeed do a raptor and here is the link Eggprops Raptor. This was done many moons ago but is still a great model with nice texturing - they used skylight for the rendering in those days sigh!
Looking forward to seeing some improvements in the animation, I know you can do the texturing
