I don't know anything about drawing but I don't think these are bad. You obviously have your own style of art going which is good! Pastely cartoonish colors. So keep up the good work! Eventually you'll get to where you want to be~
hey! i think your art is cute and has a lot of potential. however, you definitely got ahead of yourself and jumped right into stylistic work, i think you need to focus on the fundamentals of art. here's an article that outlines the fundamentals pretty well: https://conceptartempire.com/what-are-the-fundamentals/
i'd definitely recommend doing some figure studies and learning anatomy. even if you want to create stylistic art, an understanding of anatomy and form is necessary. there's lots of fun ways to learn these things, such as watching talented art youtubers who discuss them! i'd highly recommend Sycra Yasin, he draws stylistically and is very talented, here's his channel: https://www.youtube.com/user/Sycra
remember, improvement can take a loooong time. and if you're not practicing in a way that is effective, improvement will take even longer. one year may seem like a lot, but don't worry and don't rush yourself, because improvement can take many years to show. i'm not super talented or anything, but i'll include an example of my own improvement over the past 5 years, and hopefully it'll be encouraging! i think that with some more structured practice, you'll definitely see yourself improve. i'm excited to see what you come up with, good luck!
