Hello! Here is an animation that I made in your school 3D-modelling course. Rendering time was over 80 hours with 300 samples. I’ll maybe render it with better quality later but now I had to do it with lower quality because of time limits.
Here it is! (Feedback is welcome

The animation for the model seems stiff. At the 40 second mark, you can see that the armature jumps from one pose into the start of the walk. When a person stands, there’s a smooth transition for the person to start walking. The same can be said at the 47 second mark when the character starts to run. I would suggest that you go back to the animated action, go into the graph editor and smooth out the key frames by highlighting them all and press the O key to clear out all the extra date. You may have the model walking a bit smoother than before.
with such animations perhaps you should consider mo cap data?
