3D Modelling - Updated Barrel (from critique session)

Ive already uploaded the barrel that I textured previously, however, since then I've had a critique session on it and these were the points that were brought up:

- the bolts I painted on needed to be bolder

- consider added external detail (detail besides the wooden planks of the barrel) like scuff marks, scratches, stains etc

- maybe add more colour, since a majority of the barrel (besides from the nintendo logo) was brown and grey

To cover these points I just made the edges of the bolts I painted on darker to make them stand out more from the metal panel, I also added a few very faint splatter textures and marks onto the barrel to show some diversity in the texture, then finally I added a green tone to the barrel so it would appear that the barrel is very old has been exposed to a lot of water giving it this green colour.
