Took me 12 hours to finish what u guys think?

It does. Speaking from experience, the linework alone would likely take at least six hours for a proficient artist; the colouring would easily take twice that. But it's just a bot post, so protesting the OP is rather pointless. :')

Six hours for the linework?? Also speaking from experience, linework like that takes me (at most) two hours, nothing more. I find 12 hours of constant work on this reasonable.
