Nicest job, bardon, nicest job of all the time. But, I've got one more smallest idea: Why don't you do 20 minutes of 10 minute sketches, all flipped horizontally and vertical at the same drawings, if you pretty please?? Because, you'll get an even more bestest idea of drawing the figures of what you really see, rather than what you think you see, and finally, the more you put this fundamental concept into practice, you'll really master it, and it'll really become second nature in your imaginary doodles. Hope it's essentally and totally beneficial.
