Hi James,
Here's some crit on both your shots so far, I joined late so playing catch up!
Bliss That was some trip! Regarding the image I guess most has been said already, I always applaud people that take the non cliche shot or look for a different angle so like the different composition. With my landscape head on, the light is pretty flat, but like you said you had bad weather... The castle as mentioned is quite soft but this May well have been your intention. I think I would have gone for a much smaller aperture, and shot focusing a third of the way into the shot, which would give you both car and castle in focus.
Fragile like the idea and the composition, well set up, as John said I'd probably take it up a half a stop or something. But if you kept the exposure down for a moody exposure it works well. I like this, nice shot.
