I am not sure if i like the font but i will not mark down for that. you did a great job at giving yourself space for the text and the shot does a good job at saying Texas. nice job.
That's a cool looking hay barn. :D Your postcard text matches up fine with the main subject and the theme. Normally, a centered composition gets kind of hammered around here. In this case it seems to work just fine. Honestly, while the barn is cool, the surrounding area is a bit plain and ho-hum. Nothing personal, just an observation, and certainly not much you can do (could have done) about it. Good luck to you in the challenge.
