Here is my feedback. The red color for "ATLAS" does not work well with the blues throughout the rest of the piece. I think that a similar blue or contrasting white/yellow would fit better. I have the same feedback about the black and white palm trees, it clashes with the vibrant, colorful pictures at the bottom of the piece. This is very nice, I could see it being a flyer.

I really liked your picture selection but the overall colour scheme doesn't match Atlas for vacation should be more colourful and vibrant..
