There are 2 sides to feedback/criticism. I don't like criticizing other's work because it's not possible to know what issues had to be overcome to get the footage unless it was done in a controlled environment. With all the factors known it would be possible to provide feedback. Either way, you got your foot in the door, yeehaw! This is a field where you are only as good as your last work so always try to deliver the best you can do, but remember; great works of art are rarely produced on demand.
