I agree with both comments above.
You need a lot of bees and resources present right where the cells are. I doubt they will spend much effort on queen cells up top in the glass box when all the bees and the resources are in the nest below. imho - not a good idea.
As an alternative perhaps consider doing the starting and finishing in regular populous hives. Then move a few of the cells nearing emergence into your observation hive Once the cells are capped, the observation hive will certainly be able to look after a few of them. They may care for them up in that glass area but would not be surprised if they abandoned them.
If you just want to observe the queen rearing process, a good way to do that is as simple as removing the queen from the observation hive. That will initiate emergency queen cells within 2 days. If they start QC on a well resourced framer, you can then move the frame that the cells are started on up to the viewing area. Check it daily, take photographs each day for a blog, etc. They may not like it there and ultimately abandon it for the other cells they will have started below tucked away out of your view.
All in all, neat idea. However imho do not be disappointed if the results are less than fruitful.
The best observation hive queening I have had is in a regular two frame, 1 over 1, glassed on both sides. I put an old queen in it. she had great bees but had really slowed down. The bees superseded her after a month. The new one emerged, killed off the other cells, left for a day, mated, came back, and laid up a huge patch. I soon had to move them out into a full body hive and ultimately sold her as a nuc. I put another old queen into the observation hive.
