Hello!
The project is very cool, but also kinda scary because of it's sheer size. I admire your enthusiasm! How long did it take you to build it all? You have to watch one thing, though - you're putting a lot of work into this one, so I'd like to point out some minor things that you might want to reconsider to make this even better. Like putting finer chain in line with the railing - this one looks mighty heavy here:
A finer chain here would improve the looks a lot. The wiring above the "door" would need attention too - you know, little things like that. But those are easy to miss among the huge amount of work you have on your hands. That's why most people shy away from projects this large - or tackle them in groups.
I'd also like to comment on the truck - IMO the chassis is much too light for that crane - it's only capable of 2,5 tons (OK, 5 tons on paved roads). The truck in the photo looks more like 5 tons or even 10 tons truck. A straight 2,5 tons GMC in nice Navy gray would look better here.
Anyhow, I'd like to congratulate you on your creativity and energy, and I wish you good luck finishing your work, thanks a lot for sharing andhave a nice day
