It's naff. A realistic, down to colour, horse that size looks ridiculous.
I like the Angel of the North. I also like the Glasgow horse - and the only reason for not building a bigger version is that it could be too imitative.
BTW, Andy - agree about Uffington. Amazing, especially when you consider its age. It's not even a simple "cut off the turf" white horse, as most are: they cut trenches & filled 'em with bright white chalk. I cycle up there occasionally.
The Shepway one's also good.
But this thing - no. Dull, dull, dull. Franklin Mint, Cindy - all those. The only good thing about it is that the other contenders were worse. Rachel Whiteread, for example - her first cast interior of a house was good, a brilliant idea. But to regurgitate it for a commission like this? She can go & get stuffed.
