Thanks for the support and kind words all. I really appreciate them and any constructive criticism, tips & hints.
I don't think it matters how experienced or inexperienced you are, there is always room to learn from others.
@zathros - I agree that those saddle tank joints could do with a bit more work. I may well revisit those again when I start on the final weathering and general touching up once the main building work is done.
I was considering applying some nylon fishing line (super thin hook tie 0.05mm) on to those external tanks to replicate the weld lines, but I'm not sure yet.
This brings me on to another conundrum...
If I create the the railings, steps, hand holds out of appropriate gauge wire then it will ultimately look better than flat paper. However the model is still currently 100% paper.
So, this is my conundrum.
Do I use other materials in the pursuit of eye candy/and ease or..
Do I zealously make the entire thing from paper only, in the pursuit of purity. :-/
Both have their appeal..
