My submission for challenge 1. Park
Less of a park, more of a nature reserve perhaps? But this is what I thought of! Referenced (kind of) from a wikipedia photo of Chatsworth Park.
Done in Photoshop Elements with the polygonal lasso tool, the brush and some gradients :)
It is quite abstract, but I wanted to show the shadows of the trees on the water and the bank, and give an impression of distance. My trees could use some practice!
