Steampunk-Camera

I've spent too much time modelling this camera and then the materials.... The texture looks horrible. I am still a noob when it comes to texturing :/ I don't know why I still haven't fixed that issue with me..... Yeah so the textures make it look worse than it should.... and don't even start with additional rust ontop of the texture.
A little post processing has been done inside Blender and Krita.
