Well I can’t see any stitching at all so that’s the main problem that most have with pano’s sorted
As you have already said I think it would benefit from some levels and colour adjustments but these are only tweaks and should always be done last after you have joined all the images together, that way all sections are adjusted equally and it keeps everything seamless.
Other than that, the one think that I keep looking at is the left hand side of the picture…for some reason it makes me feel as though there should be something else in the view just out of frame that would be worthy of inclusion in the shot. Maybe it is because the water is cut of and must lead somewhere and the houses in the foreground give the impression that there is more of the town to be seen out of frame. As I don’t know what is really there and for all I know there could be a big ugly factory or something equally unpleasant, then it’s just one of those things, but overall it still makes the picture feel just a little unbalanced to me.
Nevertheless as a first attempt at a panoramic and for the learning experience, I think you have done a great job. Far better than my first attempt
Hope that helps Stephen
