Hi,
nice to see a built model.
Concerning the rear brakes, yours tend to 8 o´clock, (looking at the left rear wheel), my ref. pics say 10.30 ;-)).
Finish looks a little bit dull, did you polish it? - I am not a friend of Tamiya´s TS 13, but what I saw on other models was a higher shine.
The verical segments of the diffusor are far to thick, did you use them right out of the box?
Rear left and right front wheel seem not to be correct/centered in the wheel wells, maybe you can correct it.
The yellow area is well done.
