Tricky light in this image. Hard to say if it is a little dark ass all the information you really need is there. It captures the casual atmosphere of SAGE as well as a curious photographer? in the background on the blue bus. The composition could shift a little to the left to balance the dark boarders...
The color combination is nice here. I would like to have better light on the leaves (you can do this in Lightroom/Photoshop) but i like the composition and how it leads eye to the doorway into Raven 2.
Nice narrow depth of field, but the main subject still evades me...? What are you trying to highlight and how might your composition help convey that to the viewer?
