I can relate. Some of my lowest scoring uploads here are my comic pages.
Basically people viewing the images tend not to take the time to actually read a comic page, so they get fewer votes. Only a few get popular.
It's a bit disheartening when a comic page takes so much work to produce, as each panel is literally a separate art piece.
(A page for my own comic can take days to draw, for a result of single figure votes here, whilst an hour long doodle can get a great response).
