for the images, if you want to show more detail, you can still use smaller images but get closer to the model with the camera and render it out. a huge pic of the entire model doesn't help us see detail, it just shows us a larger render of the entire model. zoom in and do some renders of the areas where you think more attention is needed... and do more than one, then post them all.
as for the animation. i have no idea what's going on there. i see at the very end it looks like he takes a step, but the camera movement is TOTALLY unnecessary and makes it really hard to a) see the model and b) notice the movement. if you take out the camera movement people will be able to better critique your model in motion and the fluidity of that motion.
