I do admit, I'm still trying to improve on my lineart and I'm a second year art major but my lineart has improved since last year. As for learning how to actually draw, work with shapes and build the figure by using circles, lines, squares.
It can, it really depends on what you draw though. Some of my pieces normally take an hour to finish or even more. When I speed draw, I can finish it in 20 minutes of so. Sketches normally take me like 2-10 minutes (depends on what I'm drawing).so im guessing that one peace of art isnt gonna take an hour and a half :P
Thanks for your comment! And I drew that Cubone for a friend of mine; it's her favorite Pokémon!cool stuff man, I don't really have much critique at the moment, but I'm lovin the bright colors on the Colors! 3D paintings! Also the cubone is super cute :3
