It's nice to see this thread revived. I'd seen the 'Blue' theme, but this one had escaped me.
This next one had been shot with the 'shadow and light' challenge in mind, but wasn't used. Shot with 40D, EF-S 60 lens, ISO 400, Av, 1/125sec at f/14.
You captured it nicely. Crisp focus. Excellent tonal range.
There might be one little thing which you could do in post processing. You might crop inward from the right side of the image, to eliminate that triangle of white from the building behind. That building's diagonal line, due to foreshortening, contrasts some from the vertical lines of the red brick building.
Wow! I want to be there! It is soooooooooooooo green. I LOVE it.
Tried for some "green" today but my macro extension doesn't really do it, the light was too low, and the little bug way too tiny (some 5mm in length). But well... the photo as such is quite green, I think .
