well the only really negetive thing I see is the softness of focus on the left portion of trees, I wasn't sure if it was 6x6 film scanned, scanners dont do justice sometimes.
The run of the riverbank is missleading, I think the focus issue is depth of focus at f/3.5, the trees are running away not flat to the camera as it appears, so not wobbly hands or miss-focus.
Colours are beau, and the mist over the river is worth getting up for.
Maybe...something in the river to add a bit of a focal point and a smaller apperture for greater depth of sharp.
Its a struggle to be tough on the photo really, all things considered.
