Must Warn Others by frozen-scumbag on Newgrounds

Honestly I'd love to be able to do anything like this. It really looks great. Amazing detail and all.
I did see some things that were a little out of place, like the fallen piece of scaffolding, or whatever it is, has a dent on the side where it was less likely to hit the rock. Seems a tad off to me.
The railing on the left has a break in it, which adds great quality to it, but where is the railing? Not really that important I suppose, but I think it might make more sense if it actually had bent and ripped off the cement from the fallen piece there and was still bending toward it.
The rock on the bottom right there seems to be built into the wall, which was most likely the intent, but it seems out of place.
Finally, though I love the writing on the wall I find it a little strange that someone who was bleeding quite severely would stop to write such a thing. I might stop to write my name, birthday, etc. Or even "Help," if I were in some sense delusional.
Like I said, I can't do a thing like this, 3D art is not my thing. It's extremely well done, execution and all. I enjoy it, and it gives off a very rundown feeling to me. It reminds me of Bioshock, with a lot of Farcry feeling. Bravo.
