It sounds like a really funny group, i would love to join... but i'm tooo slow when it comes to draw and i'm busy with school.. D;
(Even though i suck at drawing - This took me 4 days to draw [link]
I think you would have a lot of fun if you joined the group! C;
But of course it's up to you, I mean you are the only one who know if you are or are not ready to join the group and be so active with drawing!
