Nice work. It's murder trying to hide the polarisation of the sky but you've done a fairly good job (though I can still see that it is a three photo composite). You have what looks like a big sensor dust spot just above the Four Seasons that you might want to get rid of.

Someone suggested to me that Hugin was a much better stitching tool that anything in Photoshop. I've downloaded it but I haven't tried it yet.

I like the spherical trick, that looks different.

DARKROOMS - whoever asked ... I tried to find one a few weeks ago but with no success. Even Qatar Photographic Society have scrapped theirs, which is little short of shameful - it shows that thar are a club for playing in rather than a society seriously interested in the art of photography.
