Very drab day. I hate to say it, but it just appears as a snapshot. not much of interest to osmeone just viewing it without knowing any background to it. The whites could have been punched up a bit to make the van appear white, instead of gray.
I'm not crazy about the composition of this picture. I like the theory behind it, but think maybe a simplified version (skip the truck) or even just a crop that shows just the top of the trees would be more effective.
