I love this. What sets this apart from other post apocalyptic art I've seen, is that this uses brighter colors and isn't desaturated. This goes against the current trend of showing doom and gloom in a post apocalyptic setting. Again, great job.
The lighting in this is very tastefully done - the warmth in the foreground and colder tones in the background really help the focus out. Great attention to detail with the vegetation too. Looks like a nice apocalypse!
