Model 1 - trinket box

I have modeled the trinket box. I have also unwrapped it.
When I texture this model. I am hoping to achieve a Muddy /greenish metal trinket bot with scratches on it. World war 2 tanks had a green armour so I used that idea for my trinket bot.
A muddy german tank. The mud on this tank is rather thick due to weather in the war, part of the story for my trinket box is that the person who owns it sometimes drops it on the ground, porabaly in some mud now and then so I want to add think blackish/brownish mud on texture.
I could proabaly achieve this if I got a brush which had spaces between the drawing area and turn the flow down, seletect a darkish brown and start drawing.I was googled green metal and this image came up. something like this on my trinket box would be amazing for me. Maybe abit less green but the base dents, scratchers and where the paint has come off are cool.


I would like to make a texture that has mud on it but still contains come shinyness to it. I can get the shinyness on the spec map, making the area I want have more colour so when the game engine renders the model the part with the spec map on it reflects brightly. So where the mud is I will not make that shiny. Scratches and dents will have more of an effect if a normal map was made with the dents and scratches on them so when view within a game engine they look better and more realistic.
