Nice job, ZNET!
I always enjoy viewing the creativity with regards to improving appearance! You should check out a post titled, "Personal Touch to Your EM's" in this forum. That thread is probably 150 entries long, with many appearance enhancing additions mentioned there.
I added color-coordinated posts as you have with some of my keepers as well, (though I have no pics). Having all white posts to me, seems to take away from the game's appearance somewhat.
On my Dimension, I added colored bulb sleeves to the top kick-outs, but left the hole inserts all white, (which probably helped with their glow). I was originally unhappy with the upper playfield darkness, so I added to the general illumination lighting by adding a 63 bulb to the upper portion of the mid-playfield center kicker plastic, (socket secured under a playfield post, wiring up through existing leaf switch holes). The 63 bulb was horizontal and positioned towards the center, it lit up beautifully. You may not need extra lighting on 2001, as the center plastic is different and looks like it will illuminate better. Funny how the plastic sets on this and Dimension were altogether different.
I also threw in red, blue, green, yellow plastic bulb sleeves, (like the ones above the top arch), on each of the existing bulbs under the center plastic, just to add color. I adjusted the pop bumpers to be lit at all times and used blue "Ink Spot" caps for them. I know they change scoring value when all 10 drops on each side are completed, but they light with the Wow's, and with Wow's lit, who's shooting for them?
Try adding 47's under the plastics behind the drop targets and slings. IMO, They have a fuller, more consistent effect. Those look like LED's in your pics with that directional, "Blotchy" appearance.
