Love them or Hate them?

Have your say about the idea of crtiques....
should you be asked to explain your work infront of other people?
do you think you learn anything from them?
do crits allow you to step back and review your ideas and work?
is there anything that you will take from each crit?
do you think tutors are fair when talking to you about your work?
!
I dont like crits atall, Lee laughs at me because i talk to fast and I forget EVERYTHING im meant to say...I SHAKE (yes I get a touch of the shakes) and more than once have gone really REALLY red!
Saying this though, I do find that crits give me something to aim for. Its scares me into thinking "right I gotta fuckin do my work otherwise i nthe crit I wont have ANYTHING!"
I do think their one of htem things like learning to drive or something that just takes practise...And we need all the practise we can get if were going art uni where their EVIL to you!
I think tutors are REALLY fair, sometimes a little TOO fair? I like critisim, and im going to get nervous wether its good or bad so I'd much rather have all the bad truthfully and know what I can work on! But then again thats just me?
