Thanks Steve, don't worry the photos with my brief comments will continue coming, Mr Dawe loves to see where his bucks are going and rightly so!
Regarding time to work and post updates, I allocate around 3 hours a day 5 days a week for customers modelling duties, although it always runs over but I don't mind, if you include research and planning our hobby probably takes up 50% of our waking lives!
I have to constantly remind myself to take pics as I work, I could take many more and go into far more detail but I feel the balance is about right.
