Is this a composite: No
Grass detail can hold a lot of beauty, and the warm lighting brings that out nicely. I like the way the composition folds around the central mound too.
Oh, I love this image. Thank you for creating an image that’s different and original and personal. We need more images like this. I’m not sure about the small cloud in the middle. I would either remove it of raise the dark areas it contains. Wonderful image.
