Strengths During this project my strength were being able to pitch in at any time and able to communicate. My team was awesome! We quickly created a group chat to communicate if anything were to happen. We worked well together and got our video to work perfectly.

Challenges Challenges during this project were minimal, there were very few point that were challenging. Like I said our team worked flawlessly, and got the job done. The only challenge was I could say would be we worked a little to quickly and didn't review our video fully. other than that no challenges!
