Looking at these, it brings back memories to when I first started drawing. It was mediocre at best lol. Please do continue drawing, because you might make some minor improvements without even knowing!
If you don't mind, I'd like to give you some feedback. You could start by making your lines smoother. From what I see, it looks like you're making small strokes to draw along a line. What you should do is gain confidence making smooth lines by doing this exercise I found on Youtube. It's helped me to draw circles better and make smoother lines!
I'm not sure if you take requests, but I'd like to see you do Agent S and Jacques together!
Also, the species swap of Marshal and O'Hare is cursed. Please do more of those to burn my eyeballs lol.
