The view certainly looks great, Neil. I guess the problem might be the haze that looks like it's flattening the images, stripping out the tonality. You did a darned sight better than I could have done!
For a first attempt (or fifth, or hundredth), these are awesome! I can barely see any joins - maybe a fractionally different tone in the sky in one or two places but that is looking really hard - and I may be wrong anyway - it's not a marked enough difference to do more than say "yeah that's about the only place I can think one
might be!" The stray bit of sensor slurm in the second is more noticeable than any hint of a join!
The haze has proved to be a killer - do you have a UV filter on the lens? and early morning tends to be clearer than later in the day when pollution levels rise

[oops - just checked the EXIF, 08:10 is early morning

I see Pete has linked to a shot from Claire. Also, Scottes was the panorama king a little while back with his shots of Boston. I wonder if he's be able to shed any light on these fore you?
