Took me a few hours to make this in Blender! I’m still learning some cool stuff so let me know what you all think!

I think you should make it completely form together without seams. With the seams and gaps, it looks odd.
So far that looks quite good, although my feedback is that you should spice things a bit up with grouping all of the parts up, which is what @automaticcorndog also suggested, making the background white, adding some motion blur, and probably changing the values of Ambient Occlusion to what actually looks good to you. And I also noticed some noise. I know that the denoising features in Blender isn’t meant for animations, but I did find an add-on that has temporal denoising, which is used for many animations, and it’s called Super Image Denoiser. You can learn more about it with these two links:
With everything said, I would like to clarify that everything that I recommended to you will cause a longer period of time putting up the new final result. If you don’t want to follow, that’s fine. Go for whatever works for you.
Looks cool, but it would be great to have a small camera movement, and maybe add more stuff to the background environment if possible.
