That shot of the tracks came out great!
Most of the shots on here show the RAZR camera's predilection for cooler colours; reminds me of Fuji film back in the day.
If you're going to do more of these outdoor scene type shots, I can't recommend the app HDR Camera+ any higher. It'll take true HDR shots (three exposure ranges combined); really opens up the contrast and colours, especially in low light shots.
