Great to finally see just how nice the inverted dome looks with a regular dome on top. I was very glad Huw had some domes in Dark Red... they're not very common, having appeared in only two sets!
The round 1X1 brick looks great nestled in the inverted dome; the three-tiered effect is very cool. Instantly makes me think of a cheesy 1950s ray gun!
One surprise, for me anyway, I hadn't realised the inverted dome has a hole in the base until I saw Huw's last picture. This will make it much more useful.
A few administrative details; the Dark Red inverted dome has an Element ID of 6058218 and Design ID (i.e. part number for all colours) is 15395. The 'doughnut tile' in Light Bluish Gray[BL]/Medium Stone Grey [TLG] has an element ID of 6055313 and the Design ID is 15535. Thanks to Huw and Brick Owl for looking these numbers up.
Huw has also taken a pic of the set's inventory page from the instructions. And his thorough review is now available - so have a read.
