No pressure on me then...!
The obvious first stage of assembly is the carriage and horses, which are the same regardless of which model you are building:

The wheels are all double sided, so make sure you get the design you want to see facing outwards - I went with the magical symbols rather than the Sigmar stylings. Then I assembled the horses too.
It might look like I have stuck the whole model straight onto the base, but that would restrict later modelling steps and definitely painting. What I actually did is blu-tack a small piece of card to each wheel / hoof, put a spot of glue on each, and then place the model onto the base in the position I wanted, Then you can remove the models:

and the base has handy markers for where all the wheels and feet will stick. Now I can go ahead and landscape the base without worryng about obstructing the model. In this case it will be pretty basic, with PVA sand and a few small rocks and plants I think.
Then I've assembled the laser cannon section of the Luminark, leaving off the parts that are common with the Hurricanum:

And then the orrery for the Hurricanum:

I don't want to glue it any more at this stage, but it does fit together nicely:

I'm hopeful that I can leave some of the Orrery unglued and free to rotate. In fact, I have only done the easy bits so far, but I'm very impressed with how this kit fits together, with many parts push fitting without glue. That said, I have started playing around with the main structure, and this is where it will get fun....
