I think the most useful video was the scaling, skewing and rotating objects video. I definetly learned the most from this video, because I never knew that I could change the size of something so easily in my artwork. I always just deleted the object and re-made it until it worked within the canvas. Being able to size an object in relation to something else and to size and object so exactly would allow me to be able to solve more problems, more quickly in my composition. I thought the presenters were ok, however they were going over the information very quickly, so I had to keep rewinding the video to understand what they meant. I also think they could have used different lanquage for a less computer-literate audience. However, they spoke very clearly and explained the concepts well despite how quickly they were explaining it.
