If you have the time, resources and ability, why not? More variety in move animations is always nice.
Remember that you can use the same animation for multiple moves. You could make one animation and give it to a dozen different moves. This is definitely the way to proceed with move animations, I think - it's more customised than the "one animation per move type" that's configured in Essentials, but less work than "unique animations for each move". After all, if you're making a new animation, you want to get the most use out of it, right?
I will say that it'd be very generous of you if you gave your animations to the community for everyone to use. Not only would it save others the time and effort of making their own animations and essentially duplicating your work, it'd also make you look like a very kind and handsome person, and you'd be much more likely to get help from others if you're already giving back to the community.
