Pete, this is a stunning image ... The colour in the sky is so vibrant and levelled by the dark ground and tall poplar trees - great composition. You achieved amazing effect here, dear friend !
This is beautiful. What vivid colors. Due to the low light, it has a lot of "noise" in it. Download Neat Image (free version) and run this through there (4 easy steps) and it will come out looking smoooooooooth and lose the graininess. Beautiful picture.
