First Time with Photoshop Lightroom

Last Sunday I downloaded a trial of Photoshop Lightroom to see if I liked the software. I really did like it but don't think I'll be buying it for a while. It retails for $120 but I found a sight where I can buy it for $90 if I show my student ID. I liked the software enough to buy it but money is tight right now so I have decided to wait for a little while. These are the photos I edited. Please let me know if you have any favorites and what you think of the photos
