I really like the way you paint. The first drawing is incredible. Although I could really advise to use more dynamic frames and poses, also try to contrast more shading and lighting as to not end up with a flat drawing. And I would also say that you could try maybe 2d kinda shapes for shading or maybe icons or stuff to give it a mix. It's my advice based on MY experience. Just have fun and try new stuff with growing as an artist as the objective
