Suprise Art!

I, as a Bachelor of Arts in MultiMedia Arts student, should be flexible and creative enough to make impromptu arts, or on-the-spot art. But I REALLY CAN'T! I am used to doing well planned art because it has less error. But whenever I do impromptu arts, I ALWAYS panic, and worst I cant think of any thing(mental block). I don't really like these kind of art because I dont want ugly arts, be cause I tend to make my art uglier when I am in a hurry. Plus, there is a TIME LIMIT! So I am now PRESSURED, which is very dangerous for us MMA students.

But there's nothi8ng I can do but to follow. So I practiced impromptu art at home by drawing and coloring an art for only a limited time, so that I wont be pressured again when the real impromptu art kicks in. But still, I cant fully do a good impromptu art. I still need more practice!
