Reflection

1-What did you enjoy most about this project and why? One thing I enjoyed about this project is working in a group, even though it was kind of frustrating, but still we had too much fun.

2-What was most challenging for you during this project and why? The most challenging thing was recording the video, especially when only two people recording it, so we had a little hard time

 3-What new skills did you learn from this project?  I don’t think I learnt new skill but I worked on my collaboration skills and I improved my drawing skills a little bit

4-Is there anything that you could have done to improve any of your skills? Explain
one thing I wanted to change is instead of drawing all the picture we could have just print them, so that we have less work to do and more time to practice, other thing is we had to be three of us doing the video because when only two persons did it, It was hard and the video looked so missy
