My performance for the CHS Girl's Tennis Baquet

Here are my 2 performances at this banquet I performed for at my High School. Lemme know what you guys think, especially about the band video. We just started and we would like some constructive criticism since we need to work on our sound. Here it is:
Performance with in the band Pure
Performance with my singer Gizelle

Oh and sorry for the bad video quality. One of my friends recorded.
