To be honest with you, I think you should be focusing more on the quality of your sprites rather than how many sprites you can make.
Yeah it's great that you are posting more content but at the same time you do that the less likely you'll be able to improve on what you can already do. Maybe this isn't how you work and that's one thing, but you shouldn't be afraid to go back into something you already "Finished" to improve upon what you have already done.
There's no such thing as a finished artwork, and that logic applies to spriting and pixel art as well. But on a brighter note I do see the potential you have and it's really just a matter of bringing that potential out.
