Hi there!
Overall, it looks good to me, so good job! I particularly like how you managed the handle’s bending when it starts to spin, to me it really looks like a living neck.
I also have some things to point at:
- When nothing is moving, it looks kind of dead, or even wrong.
When animating in 3D, you really want to avoid perfectly IDLE stands, because it looks wrong.
I.E. frames 030 - 037: I would suggest you bend the handle to the left from frame 028, it would look like the handle is dragged by the head and have a hard time not falling with it.
Another simple thing would be to add some paced bendings, like a breathing, it would make the whole thing look alive, and you can play with that: when down, I breathe, and I take a big breath just before doing an effort. And when I’m done, I breathe faster for a few moments.
- Overall, do more anticipations
Just an example of the very first movement :
Imagine you are the handle and the head is a big heavy load laying on the ground. The first thing you do is to bend a bit more in order to get a better angle of action, then you start to raise up, your muscles straight up, and then the heavy load leaves the ground. In real life, it looks minimalistic, but when you’re animating in 3D, especially something supposedly not living like an object, you have to exaggerate everything.
This is exactly the kind of thing you can do, you can make the handle bend first, then take a few frames to make it look it struggles to raise the load (which will make it look and feel heavy), etc.
You really can go razy with that. And again : good job!
