I love the trees and the sky in your oil painting. Honestly since I do painting I didn't even look closely at the pastels. I see where you did get smaller as things, including the road got far away, but there are other things you can do to make it more realistic. Things far away are always lighter and less distinct than things close up. Also I feel your transition from here to there is too sudden, a gradual reduction instead of a sudden reduction in size would be more realistic. But honestly I think you have lots of talent and I like your work.
