*agrees shaking head* This happens sometimes to me too
When that happens I try add a cool background or something, or try to imagine the situacion of the drawing, then you might see what you're missing
I mostly make drawings with my imagination so I usually don't have this problem 'cause I keep putting random stuff. ( Sorry if this doesn't help at all....... Welp, Merry Christmas! )

Yeah, I know what you mean.
Just don't go too long on an artist block.
And just keep on drawing trying different styles.
I just keep doodling.
I asked for help on newgrounds forums, and no one seems to be answering me.
But I still draw what I like.
