Today, a special Festivus fueled edition! The featured bots, SS86 Brawn and Perceptor! 
Much ado has been made about the SS86 series in general and it's faithfulness to the Sunbow designs. Perceptor has actually had some good representation over the years but Brawn has never quite hit the sweet spot until now. Both are accurate to the clean designs used in the TV series and the Movie.
That's all well and good but I like a lil' more meat on my design bones. ToyHax provides, restoring the toyetic charms I so love.
Since this is already running long, we'll skip the before shots.
Let's start with Brawn, in BOT MODE.
Standing brawn shot here
ToyHax plays it lowkey, providing accents throughout to break up the yellow and green with spots of blue and metallic accents. The set includes a silver gray chest decal with horizontal lines, but I have no idea what it's referencing and left it on the sheet.I stuck with a new Autobrand with a chrome backing.
Headshot
Zooming in, Brawn's backplate gets some vents and pops of green to help break up the yellow.
Back and side shot
Brawn's set also includes plenty of pin covers. ToyHax has been doing quite bit of this lately.
RANGE ROVER MODE
Angled vehicle shot
A nod to G1 Brawn and his origins, The Mysterians M is restored to the hood. The windows get reflective cel blue, and the turn signals and roof lights some relfective gold. 
Front view, side view, back view
Some silver picks out the bumpers, plus  BR4WN vanity plates. The gas can gets an "X" to help it stand out.

Moving on to Perceptor, BOT MODE
Body shot
Our resident scientist has many options in his set, allowing for differnt iterations of the IDW MTMTE take. He also has multiple labels for his chest panel including "slides" for microscope mode. I declined on these options myself, hewing closer to the G1 toy look. 
ToyHax keeps a light touch overall. Greeble on the upper legs, dark bronze on the lower torso, a pop of silver in the crotch joint and the light blue under the chest window. His knees and lower legs regain their silver and red accents.
MICROSCOPE MODE
Microscope shot
Perceptor's dials get re-chromed and his scope regains it's signature Autrobrand. The legs on the stand get their greeble labels back, breaking up the red. The tip of the scope also gets a pop of chrome.
Side shot
Under the dials are various magnification displays, plus an additional scale on the scope barrel.
BULLSHI- SOLAR TANK MODE
Solar Tank shot
And for you lovers of fan modes, the "Solar Tank" gets some dark bronze for the treads and the connector piece for the "gun barrel"
Both sets are excellent upgrades and, in Perceptor's case, allow for varying levels of customization. Highly recommended.
Many thanks to Kirin for the wonderful gifts.
