Looks nice. The concrete looks like it could use a little more bump to it and I can see the topology in the bend. If you used a circle to make the concrete, try using 64 or 128 sides to make it smooth. I do love the composition. The sun in the sky and the clouds are a great touch very well done.
I do enjoy the textures that you used, they don't seem to have and edges that are visible. The bench does look good, but it also looks like it needs a bit more detail or support. Good job thought I like it.
