Beautiful photos, and good advice too. One more comment. Actually two. It looked like you put all the empty frames on one side of the hive, generally when I upsize into a larger box I put the existing hive frames in the same order in the larger box and fill in empties on both outer edges.
2nd thing, entrance reducer. Little scrap of 1x2, wadded up tin foil, anything, you need that entrance not much over 4 bees width and one bee height at this time of year in a drought in North Texas, or you can lose your small hive to a robbing larger hive pretty easily. Particularly do not add any essential oils to your feed, do not use HoneyBeHealthy, etc or it is like a flag that says "rob me". Except for my largest hive, all of mine are on entrance reducers turned to the 2 bee width, low height, just enough for the undertaker bees to be able to haul out bodies. There is a little traffic jam from returning workers but not too bad. Also take care not to spill syrup or honey and watch for drips..
I fought a large robbing hive for over a month before losing my second hive (at 7 frames) to the robbers. At the time it was my only hive. Heartbreaking and frustrating. It was something like October 3, 2011, so around this time of year.
