Duke Collage

Thanksgiving weekend of last year we took visiting family for a little tour of Duke's campus. These were some pictures from that day.
I had been wanting a new large piece of wall art for over my couch. I found a piece I liked okay and after mentioning it to my friend, she suggested I try to make my own. I knew I wanted to make a collage somehow but wasn't sure how to go about doing it. I finally decided on using Walgreen's collage poster option. I chose the pictures I wanted to use, and it would shuffle them by size and placement until it got to a configuration I was happy with. After tax and shipping it was $30 for a 20 x 30.
To have it custom framed was going to be over $150 after coupon, so instead I bought a frame at 55% off for ~$30 and had a mat custom cut to fit it for ~$20. I am very pleased with how it came out. (By the way, the reflection on the glass of me taking the picture, and also the mantle, is making some of the images look a little off...and my walls are not THAT dark.)
What do you think?
