This is a project I started about a year ago, and never finished. I've come back to it in the last week or so and took the decision to start over. Even though I made some good progress previously the topology of the model I had was looking a little messy and I was finding it hard to work with.
This is my current progress on the new version which I am already much happier with. The mess flows much better and feels more optimized. So far I have blocked out and worked in all the major details and now working towards some finer details.
