I this unit I learned about forced perspective and what it is. I also improved on drawing cubes. I think that I can still improve on my drawing skills.
My opinion on original art is that I don't think that anything is necessarily original. You may have created it but there is probably something already out there that is similar. I think that not everything in the world is really original. Just because that it say it's the original... doesn't mean that it's actually original.
Some challenges I faced were that me and a group of other were sent to take forced perspective photos and we had trouble coming up with ideas eventually we did though. At the end of the unit we had to draw something or put something up with tape I chose to draw something. I drew squares that lead into an abyss.
