If you're going for sunset try the golden hours, you get a lot of depth and cool color variation.
Like colder blues at the bottom and golden yellow/orange at the top of the buildings. (If you do a small city-scene)
It's important to try and catch that initial feel, with the lighting it should be a great range and only top out (and get over-exposed) at certain points. Right now everything is red, try to get some more range in the colors in the scene so that your color information in your textures don't get lost.
It's just my opinion though
keep working hard , looking forward to more!
