I like your cars, Javier. You are really good at drawing them. I don't know how you manage to draw all those straight and curvy lines and make them behave so nicely. I guess it's because you have a deep understanding about perspective? ^^
Anyway, very nice art. Show us more :D.
I have a problem in my eyes. When I look through the corner of the eye, I see curved lines instead of vertical ones. It helps in my drawings.
