James, your AEG is looking good.
It is nice to see someone else tackling this subject, as not many are being shown online so far.
There are a couple of nice builds on the WNW site.
It is great to see an early version too. The model goes together quite quickly and the build is very straightforward.
As an aside,
Have you got a copy of the Windsock AEG special as a reference?
There are some good building tips inside along with some great archive pictures. Ray did a really good job with this special, and it is an interesting read, including the forward by Sir Peter Jackson himself.
