without a step by step it's a bit difficult to guide you.. I can see you burned and dodged.. and I'm pretty sure you texture placement as well.. the only thing I could suggest is to cut reflection strikes with white paint and try to place them where a mirror/metal flash would be and then play with the opacity (the white flash is that shiny thing on a sphere or an eyeball (Like the window shaped thingy on the eyes of the PXL Logo.. it give Objects a shine surface depth.. (You can gradient them as well.. experiment... (I'm okay at them but I AM not an authority by any means.. I'm sure others will have better Ideas.. I'm just voicing what I would do at your request.... good LUCK AUTHOR.. very good work)(sorry, I was so much better at this with oil/acrylic paints LOL, having a back light constantly always screws me up, It's like trying to play piano under water)

looks like hard work, and the roof is very convincing, but i just don;t believe that it's metal. Try adding a reflection, or making it shinier.. there are lots of tutorials on how to create chrome objects, try something like that, but a little toned down. Other than that, it looks like you put a lot of effort into this, so good luck!

OK................!

thanks for all the comments, ill try and add some shine if i can. and as for sparklen that was a very informative comment was it negative or positive ?
