What kind of photography should I present?

[Jordan]

I'm trying to get into Tennessee's Governor's School for the Arts this summer, and I have to present my portfolio in mid-January. My area of interest is photography, but I've been told I only need to submit 2 or 3 photos. I'm pretty good at photography, but my question is what kind would make the best impression? Should I use some that show especially good composition, or especially good colors/editing? What would be most impressive and convincing that I'm good at it?

My photography instagram account is @thousandwords_jem. That's not all my photos of course but it's a sample.

If someone could please, please, give me some educated input that would be amazing!
