Yeah he's right. You shouldnt do these 5 minute pictures and submit them, because remember 2Draw is a FREE service. It costs them money out of their pockets, so that we can draw here for free! So do some good work or we might have to start paying o.0
Not saying your work isnt good. This fox looks great, but you could take more time and do some shading and add details.

When i spend less time, it doesn't submit it. And I just lose points. I don't know how you send something less than 30 min. because it never lets me do it. That's why all mine are at least 30 or 33 min or so, most of the time is thinking "okay what can i do now? I have so-and-so time left until i have 30 min done... what can i do...!?!". I don't understand how ppl can do it. But I agree, your paintings are good, but you will lose pts if you have it less than 30 min. Not fun. What i heard is you can't draw nemore if you have less than 0 pts. (basically if you have NO pts, you can lose your privilage to paint on 2draw! :( that won't be fun!)
