WIP Tripod over house, Again

I’ve had many many posts of this project all after going back and touching up as i get more experienced. Here is my most recent attempt. I’m somewhat stuck from here. I’m going to go back and fix the tan part of the house to match better and fix up the chimney. Aside from that I’m not sure what to do with the actual tripod. I want to add detail. How do i make the metal more metallic looking and how do i make the green part look like real glass?? I want it to look more realistic so any suggestions would be great.

Happy blending…!

Thanks! Any advice on reaching that next level of realism?
