Looking good so far :yes:
There are a few things that stand out to me that you might want to change:
1.) The lighting in the sky is too focused. One part of the sky is significantly brighter than the other part. Now, of course there are variations in the brightness of the sky, and since the sun is closer to the left, it makes sense that that part of the sky would be brighter. I just don’t think it would be quite that noticeable.
2.) This is the biggest thing that stands out to me (but it’s the second on my list, for some reason Ah, well); the lighting is still way too dark. It’s daytime; the sun is still out, and you can see it in how bright the clouds are (I know that’s just an image texture, but you should do your best to match your scene to it anyway). The sunlight wouldn’t be that dim; at least, not with shadows that sharp. Don’t be afraid to crank up the brightness. I’m guessing it will probably mess up your sky background (I think I can sort of see how it’s set up based on how it’s been changing with the rest of the scene up until now), but focus on brightening the scene first, then work with the sky.
3.) There aren’t enough pebbles. Now, I know you just removed some of the pebbles, but there needs to be more size variations in the ones that are there, and maybe a few piles of them on the side. Right now it’s like there’s one pebble that’s scattered across the scene, no size location or variation in distribution.
Other than that, I would tend to agree with everyone else in that the road and the rail are too straight/uniform, and need to be a bit more bumpy/deformed.
And as far as the idea behind the image goes, I suggest you create one. You could have a part of the guard rail missing and skid marks on the road, implying that a driver missed the turn. Or maybe something else that’s not quite so morbid As long as it tells a story, this image could be improved drastically.
I’ve created a really, really, simple mockup of what the new lighting setup might look like. This is about the brightness that I would expect an image at this time of day would look like. Excuse the poor photoshop job; I didn’t have much time to work on it :spin:
That’s all I have to say; I hope this helps, and good luck on your image!
