Looks like a good mixture you have there Willow!
I particularly like the second screen.
It is great work, and even better that you're contributing to the community so often as you do, but to offer you some crits on the last screen as you asked for;
The floor doesn't match the walls too much. The floorboards need to be darker, atleast enough to match the panels on the wall texture. The wood on the wals (i assume its wood) is quite repetitive. While it does tile, it tiles in an ugly way. perhaps you could try extending the beams to cover this up, or experiment with other textures/tiling there?
Just a friendly suggestion, I do not mean to criticize you too harshly, only to help you improve your work.
Keep it up!
I think your style would suit a SciFi theme well! I'd love to see something like this from you
