looks good, maybe a little 2 clean. what I use to dirty up my armor and helmet etc is you take some alcyd based paint (although i think it would work with any paint) and ( * i dont know if this is an english word aswell) you put some TERPENTINE* on a blanket and you rub that through the colour of dirt (grey or cark green or dark blue or simple black) and you rub it on ur piece, keep rubbin'it untill you achieve the level of "dirtiness"you prefer.
or you just spray some of those colours over it again from a large distance, creates great misting aswell, after that i always bring up the silver parts again, that way you have 2 colours of silver, one dulled, one bright, makes for some great beat up and worn weathered look. :cheers keep up this kinda stuff.
could you PM me on where you got these knees and what you payed for em etc, I still need knee pads, goin to do some dummys of cheapo plexi-glas, but atleast I'll have soemthin around my knees that way.
