It's not really captured Prescott for me. That could have been anywhere. There's opportunities at the start, old sheds, buildings, men with white coats holding the chicks to stop cars rolling backwards.
Then the wooden fence separating cars from spectators, the crazy uphill hairpin and the the wooded section.
Then there's the old cars, the competitors, the hilly pit area.
The bluebells adds a nice element, I think you cropped too tight on 5&6 as it would be nice to seethe sweep of the track with the cars. Also a polariser helps cut the glare.
Out of them all, I really like Number 2 for all the above reasons.
