Nice work on the figures, and super solid perspective on the car! 👍🏻

Hey oscartampuipui, I noticed that no one commented on your post, but I wanted to say that I do these quick sketches all the time. They are really helpful, and I suggest you keep doing them. I think you should slow down and make sure your proportions are more accurate. Also, keep the gesture in tact when doing these sketches. I did some sketches to show you what I mean, hope this helps :)
