Thats just amazing. I am new to this site so I am learning all the time. I had been thinking 'would fishing line make good hoses and wires?' (I am a fisherman) yours is the first build I have seen using it (I am VERY new to the site sorry if this is an old trick every one uses, new to me).
Along the lines of the fishing line trick I have also been thinking about trying some braided fishing line (like Power Pro) to simulate wire looms and what not due to is slightly textured surface.
Like I say though, great job, Can't wait to see that green once its sprayed.
