Hello there fellow deviants,
Perspective is probably one of the most difficult concepts in art to grasp. I suppose pretty much everyone has or has had problems with it, even some more experienced artist. I can tell you I'm not exception to that. Even thought I wasn't extremely bad at drawing, it still took me 6 years to even figure out where I needed to work on before I could address the deeply rooted issues I had.
I have basically based all of my artistic understanding on perspective and 3D. Although I can't say I'm perfect in my execution, by looking my gallery you can see that pretty much all of my drawings tries to convey the feel of depth and 3D. I think that's one of the factors that make my drawings stand out and maybe you also feel that way. Drawing depth has become a second nature for me.
You may also have noticed that I have about four tutorials (depending on how we define perspective) that tries to explain a thing or two about perspective. I have also few practices/demo
