As I alluded to above, I do hope you're taking these at a high enough resolution that they can eventually become art! Yes, I think they look that good. 
Cheers Craig!
I think I'm covered with the resolution/file size mate 


@300dpi (a normal printing resolution) that's about 11.5" x 17.25"... Hmm, well that's close I guess! @200dpi it's about 17.25" x 26" which is better, but may not be as crisp as you'd like (200dpi is about as low as you really should go resolution-wise). Of course, you could always put one of those huge mattes around the smaller image and fit it to a larger frame too!
Do you have the larger sizes posted anywhere? It would be fun for some "deep zooming!"
