The back palte still looks similar to the shrubbyswan one I'm guessing for your new plate you traced similarly to what they made but that's in part, where the issue lied. You'd be much better printing off a boba or jango template and trimming it to fit that back plate,
the collar looks good but can't really tel without the rest of the pltes, looks a bit rough at the bottom edge but could easily be passed of as damage,
and with the knees it looks like you've came into the same issue as shrubbyswan, you're puting single bends in the corners, what you need it a gradual bend over the centre of the knee and leave the sides flat. what I did was heat up the main knee plate, leaving the side tabs cold, I then curved it round a 2 litlre bottle of coke. it gave the centre of the knees the needed curve, but left the outsides nice and flat, and the transition from knee plate to sides was gradual instead of a sharp curve,
