Hey, that’s incredible for early work. The elbow pops a little high at the first “give” which was a bit distracting.
The biggest problem that I noticed was that you don’t use moving holds. In 3d, unlike some other mediums, when your character is perfectly still, he seems to kinda drop out of the scene. The best thing to do is to make him move subtly when he’s “still”. Stuff like shifting his balance slightly and fiddling with something can help… even the slightest sway, as long as most of him is moving.
Also, while you have some great poses, it feels a bit “disjointed” at times, like just his legs are walking, or his arm is giving but the rest of him is reading the times
If you plan on getting into animation, get the Animator’s Survival Kit. It’s better than sex. Well… it’s better than animating sex.
