Good job firstinaction. It's the best work I remember seeing you produce. Some ideas or tips to help:
1. The overall grey is a bit boring. It may be personal preference, but I think its a bit too simplistic how you did it. Karith used mostly grey and looked good, but it wasn't just one shade, or one layer. Try to add more variety.
2. The lighting in the first two pictures seems monotonous and a bit too dark.
3. In the first picture, for the warning stripes and the grey raised blocks inside it flanking the ramp, try beveling it, you may be amazed at the improvement in looks. Especially the grey brushes alongside the ramp. Try even a 45 degree angle cut into the lip. Try maybe lowering the hazard lines a level and beveling the brushes around it to line up.
4. Second picture is a bit too dark and gives me this feeling of monotony, even though it appears well done. Try adding more "pop" by changing shades and colors and adding some more details. Also, minor note, that brush appears to be going through your HUD?
5. In the third picture, there appears to be no light coming out of the light fixtures except at the bottom and it just feels off, and the textures seem too scaled up. Try reworking the lighting to make it more dynamic and better matching with physical fixtures. Try creating a trim which lines up the light fixtures (parallel to the wall and touches the wall on one side, and ends on the other side at the inner edge of the light fixture, running down the hall. Again, you may want to consider sinking the hazard striped brush just a bit.
Keep up the work. Just try to make the textures and lighting a bit more dynamic, varied, and effective.
