the title reminds me of a book called 'tomorrow when the war began' actually the cover art for that book is really similar to your picture, maybe thats why... tho i like your picture better then the book's
That... looks like the Calgary Stampede xDD I wonder, is it?
Aside from that, I love the colours. It's absolutely beautiful and makes me want to go to the Stampede despite avoiding it. Ah nostalgia. I'm definitely going to have a look at your other work, as this is stunning!
