Hi Pilot

As far as the clothing goes I would say that it needs to be a made looser in the areas between the armour, as it looks very skin tight like a scuba outfit at the moment ,by loosening the cloth areas will enable you to cut your mesh a bit more and stick in the extra detail that you want to create more realistic creases, once I get home t,nite I'll post you some cool reference of Jango to have a look at
