Oh yes another thing about pixel art....I've always associate my interest in Lego with pixel art..when you have to turn a complex 3D object into a number of grid/blocks, you have to make a lot of choices and some of them ain't all that obvious, it's all about finding alternative way to describe what technically can't be reproduced,the difference in one pixel might give very different impression, pixel art is a very good foundation on a 2D level, and Lego is a step up, I'm a huge fan of the old school lego blocks, and build very traditionally - from the ground up. It's very abstract as very often I have to use a single block to represent something complex, like piston block, a brake duct, however that's where the fun is, it challenges your imagination on the possibility of a single block.
