So I try to do every part of the process with 'sketching'. I changed my sharp lines to a pencil-like and I basically don't care if a line is not perfectly where it should be. I do the same with coloring, lighting, everything. That's how I went from example 1 to example 2.
That's why I got 50 of this (1) while only got 1 of that (2). And that's also the reason for doing only character drawings (without environment) once I got a little further than a simple sketch. Hhhh...
