Makes sense - like, maybe each month you can submit a certain number of pieces and you get points for that amount - OR - you can submit as many as you want, but you have to choose a few that you think you can get a lot of points out of. I feel like the second one encourages others to improve on certain things. (ex. if i made like... 20 pieces of art, i would choose 3-4 that i think could get me more points, look at the others, and kind of think "hey, i need to improve on ___." or something like that. My way of thinking is odd. It could also kind of help others look at my art or other's and think "hey, maybe i can take this element and put it in my art." i dont know.)
And hey, I'm full of ideas. I can always throw input in when it comes to my mind.
