Not keen on the red calipers. I done the same to mine and then painted them silver.

Grille is nice though.

Good effort

Looks good, I think the red caliper mod is a typical marmite discussion, I did mine exactly the same way you have approx 2 yrs ago, got some white BMW stickers to give a bit of contrast, personally think they look great,&, as they say beauty is in the eye of the beholder...
With regards to the grille I also plasticoted the chrome outer, again this is a marmite mod, some hate it...photo shows both mine & Greg's cars.
