This movie was such a great movie ! . I haven't sketched for a month or so , yet when i saw this i decided to be u to the challenge. It took 5 hours 30 minutes. I used HB, B, 4B pencils . The toughest part was sketching one of them upside down and lacing it all in one small A4 sheet which was kinda tough but hey, managed to finish it.. Suggest what to sketch next !.
