Towering Colour

A bit of a field test today, and I'm not sure what result I really want. This is taken, slightly edited and published on my first ever "smart" phone. Having paid for it, I want it to be good but if it's too good, I'm going to have difficulties justifying my equipment going on holiday with me. I still can't quite get my head wrapped round the fact the screen on this phone and my 27" iMac(2011) are the same.

EDIT: Seems I can't upload the original size from the phone. Not sure what I have to do but this doesn't look so good on the Mac as the original does on the phone.
