Beautiful pictures, U-96, thank you for sharing them!
Pictures 1, 2, & 4 are intriguing because they showcase the Speed Blur affect! The car frozen in time, with the wheels, track, and wall blurred.... which is an excellent way of displaying a model, giving it an "In-Motion" affect even though it's static.
I experimented with this technique last year, using an AMT '71 Monte Carlo.
Thanks again for the pictures!!
Take care,
Frank
