>>29702740Anon as an art major, I'm going to give you the same level of critic that we have to give each other in college.
Your lines are too hard. You need to focus on the flow and movement of your pencil. Start doing gesture drawing to get down the positioning and pose of figures, even if they are just Pokemon. What you have here is a finished drawing with no base, sloppy shading, and uneven proportions. It's not terrible, but it's not going to get you into animating.
There are a lot of tutorials and practice material you can use online for gesture drawing, and buy a non photo blue pencil to start doing under drawings. Trust me, when I first started this all sounded silly, but 5 years later and I've learned it's a life saver.
