Need feedback.......

The texture is what stands out to me. Everything is straight rust with very little variation.

Usually things don't rust to this degree, and even when they do, they rust in a particular order. Water collects in corners and where the paint is being stripped back, causing severe spotting in pointed areas. Flat surfaces degrade but rarely rust into this bright orange color.

i will improve

don't know if i would trust it with my post! Also royal mail wouldn't let one of there post boxes get this battered!

I totally agree with ysalex, there's always an order to nature's chaos. Also, scratched corners and edges really go a long way. I'd still love for you to post your textures.

Shouldn't the bottom part be concrete and not iron?
