I know how you feel. I would reccommend doing something else for a while. You may not realize it but you may be getting tired of Colors. I'm sure your friends would understand if you put aside Colors for a little bit.

i would say try the contest that are in colors

its under color news try it also to get in the groove i draw on paper with a pen or wood pencel turn on diffrent music then you normaly lisen to keltic or regea or death mettal and draw how it makes you feel or what you think of when you hear it. drink some hot coco or water with five drops of lemon or lime in it

Wow, that's happened to me before.

Just relax and uhh... doodle stuff.... uh... Yeah I'm no help ever sorry for wasting ye time bye.

I never get art block that lasts very long, but it's good practice to occasionally (or frequently) step away from digital art and challenge yourself to do more traditional art. Personally I think that it's harder to improve your art in general if you only do digital art, but this is coming from someone who is considering professional art as a career, so... :/

This happens to me sometimes, just try drawing sketches or something you like and it will eventually lead to something

Something that helps me is jst absentmindedly doodling my favorite characters. Usually that gives me ideas or I just like what I drew and make it an actual picture :)
