On the gray, I would darken both the cod and the knees. They are almost white, at least in the pictures. For weathering, I am good with it as is. You could go the more sandy style which is a little more realistic looking, but this is definitely approvable. For consistency, it would be nice if the cummerbund had a little weather as well, but not the end of the world. One pouch doesn't look like it is closed correctly. It looks like it would close correctly but not sure if that was just misaligned after it was opened last or if pouch closure is off.
