Just a quick update (away from the actual model). On June 7th Jean Li gave me a guided tour of the Egyptian collection at the Royal Ontario Museum. I was able to snap a few pictures which I will be able to use as reference.
A few gaps were filled in. At first, I thought that it was a khekerfrieze on top of the screened elements between the columns. I was able to get my hands on the original print version of Rankes illustration of the front of the temple, and it appears to be a repeating Uraeus relief (similar in style to the pic I took at the ROM).
At first I thought the details along the cornice was a Khepri scrarab, but after discussing this with Jean we’ve come to the conclusion that these are more likely to be a series of cartouche.
I’ve incorporated some of these modifications into the front of the temple.
