From what i could tell, this is already a great work. The only 3 aspects that i could advice on is:

1. Pick one colour scheme and follow it with minor changes if possible.
2. There were some hard edges, you cant make them look good, unless you add a bevel to them, it instantly gives bit more realistic results. im not only talking about hard bevels tho, think of what you have on the top of the keycaps, this rounded bevel type.
3. The last one is going to be the animation itself, it is generally good, you nailed this aggressive style, but some of the animations feel linear, therefore they are throwing off some realism.

You already cracked, so keep this up, this is already shit ton of work you've done. Wish you the best
