okay, here's what I'd do:
1. First look up an image of a dome that's a pretty close fit. I'm going to presume you can't find a dome you don't find a dome you can just plop in. However, still use it for getting the perspective correct. Use it as a guide for the next part. (scale it an place it in the background for approx perspective)
2. Google up a metal texture you like (I'd stay away from glass unless you know 3d or have lots of spare time... ). Now go through each square of your grid and cut out a metal square that approximately matches the size of the ones in your reference image. Each square should be on it's own layer.
3. now match the perspective. On each square layer go: edit>transform>perspective. Play with this till the grain of the metal matches the perspective of the grid in your ref image. I would then scale your square a little bigger than the square in the ref image, and later isolate each square with layer masks.
4. Add an adjustment layer any color correct for a darker, base tone. As it there's not much lighing.
5. For lighting: copy each square and group above the original layer. Set it to 'screen', and add an adjustment layer>curve. play with the curve and the opacity of the 'screen' layer until you have the lighting right for that square. The sqares nearest the light source should be super bright. Additionally, since you already have a lit BG, you can overlay this base image on top of the metal dome and set it to screen or overlay (play around this these two modes).
6. Do one big color correction over everything. I'd recommend just copying the base layer, setting it over the entire image, and then setting the mode to 'color'.
That's a rough of how I would approach it.
