For starters, this Industrial Revolution isn't even close to 70% complete. All of your screenshotts were on the 1880 Steam Boat which makes the slides as if we have already see them already. Try building something else like a port or docks, factory, or maybe an underground railroad through a tunnel. There is many possibilities out there and it looks like this could be built in like 20-30 min. You need to wow the crowd if you want people to give you diamonds. If you improve it, people might give you diamonds but now, get working!
