haha well we're all working towards improvement, everyone is different.
I know more about graphic design than the animation industry, but I think it's a given you have to be somewhat good at drawing and creating characters/ concepts. Understanding the technical side of things will also help you a lot and give you a big head start, so maybe look up industry standard software and see if you can try teach yourself before you start studying?
I think your sketches look great! Just keep working on anatomy and perspective and try to figure out what you want to specialise in early on if you can (so you can focus on getting good at a particular thing).
I follow an artist called Goro Fujita - he's a great artist and works in the animation industry. I definitely recommend you follow him, his concepts are really imaginative and fast (a trait which I'm sure is important when working in animation).Websites I like include Creative Bloq and Digital Arts, although there are loads of similar lesser known pages that have valuable info. Hope that helps you ^^
