Excellent perspective and I like how you keep your lines loose, yet confident. Great great work, luisC!
Thanks Dmitri. Actually that was my intention, be as loose, as relax as possible while maintaining proper perspective. But that's a difficult balance! I am thinking to do this kind of page as a warmup exercise.
Yeah, perspective is very tough. Takes a lot of practice to start feeling it. But your sketches have good perspective, so it's probably a matter of mileage for you.
