Here is version 1 of the TIE Silencer based on all of the revealed photos and taking some design techniques used in the official Lego set primarily to use the printed pieces. It looks like the hull should primarily be dark gray but The printed hatch that comes with the lego set looks to be black... I'm still tweaking a few areas and playing around with the distribution of black and gray on the hull. Shout out to RebelBuilder, as used some great techniques on his early model based off of just one leaked photo (I kind of like his design better than the official design)
