DP2M Stitch Time

Looks good to me.  Try as I may, I can't see any signs of where you stitched them together.  Nice job.  Not sure if it matters, but I'd straighten the horizon, unless you were just using the image as a stitching exercise, then it's irrelevant.

Impressive amount of detail, even in the distant buildings.  Look forward to seeing some of your twilight/night time city-scapes.  The ones you posted in the fuji forum were impressive.  Will be interesting to see how the sigma compares.  I like to shoot similiar images, and was wondering how the sigma would perform.

Keep them coming.
