Thanks for the feedback
Hmm, I realize that after today's sketching session I've only gone through 43 sheets in 2 weeks (not including warm up sheets)... To go through 500 sheets means I should be doing 32 sheets per week... need to step it up
I tried to fix/understand the perspective... it's not often that I draw rotated cubes... I understand where the cyan lines come from, and the dark blue, but the YELLOW one...? Is it estimated from the length of the equal length "verticals" in light green + parallel to the top cyan perspective line?...
Tried to draw some boxes on larger A3 (approx twice letter size) paper. I didn't realize how rusty I am, could use more perspective boxes practice...
Tried to draw the computer thing with Staedtler fineliner on paper. Took a few sheet of paper before I set up the proper grid/perspective. Was hard to get any contrast/pop with the dark fineliner so I tried to use a sharpie to outline... hmm.
