there are a lot of ways to get over art block >____< the only problem is finding the one that works.
when i get art block (like right now lol) i usually look at inspiring artists sketches and finished works and try out some of their techniques. Another way i get over art block is putting on my head phones, pound some music, and draw like crazy of whatever even if it just starts out as eyes and simple things, i keep going until i get into the flow of things >U<!!!! There have been times where I've literally drawn for twelve + hours non-stop, 0___0 (especially back when i had time lol) most of the time they are all sketches tho =____=
