I'm afraid both problems are still there, though the new shadow from the turret is a big improvement. Here's a rough edit just to make it clearer what I meant:
The form of the creature's torso isn't really changing, so the shadows should be the same from frame to frame (assuming a distant light source anyway, if the creature is lit by a lamp dangling right above it, that's a whole different story). In other words, you created a lot of unnecessary work for yourself in redrawing the shadows on the torso in each frame xP
The shadow from the torrent-friend is more foreshortened and horizontally squished when it's cast on the top of the creature, and more vertically stretched when it's more on the side of the creature, so the creature looks more rounded and less flat. The shadow should probably be placed a little differently because it looks like you meant to place the turret on top of the creature and centered, but the shadow makes it look like it's leaning to the side. I didn't remedy this in my edit, I just worked with the shadow where it was. If the turret-buddy isn't moving from center to side and is staying in place and only rotating its head, then the shadow should not move, just slightly change shape.
I got rid of the yellow highlights for ease of editing, but like the shadows, the highlight should not be moving around so much relative to the body, they should be moving
with the body.
