Awesome print! Looks like you really have your Tevo LM dialed in! That matchbox copper looks like it has great sheen! Now is it just copper color or does it have any copper fill as the Colorfabb copperfill does (80% copper)? I've been looking into a less expensive heavy PLA option. I have also bought the Tungsten from REPKORD METALIX 3D. But I have no idea how much tungsten if any is in the filament as it doesn't weight any more then standard PLA? I've also had problems with layer bonding. I've been printing at 215C may need to experiment a bit more by bumping up the temp.
