I would ask a question about your choice of crop on the first photo. Typically a landscape photo tends to be wider than tall. Doesn't have to be, but that's how it often works. Why did you choose this crop...and is it accomplishing what you wanted? I find it too narrow; makes you feel claustrophobic...an odd feeling for a picture of a "possibly" wide horizon and broad field.
The second photo is a great setting, but lacking a dominant subject. You have to love that tunnel of greenery...just need something at the beginning to capture the imagination!
I think the exposure, saturation, focus, and overall appearance of the photos to be fine...and to offer a great deal of potential. Thanks for sharing. Am looking forward to more of your shots.
