not overly hard to pick out that the top isn't the tunnel, as there is a colour change between the added canvas, and the "road". The added canvas is the same colour, top and bottom.
Good work though. me likey.
As for this poll: 2 BMW's, what a co-inkey-dink. After much deliberation, I had to choose NTX's (I'll assume) shot. it looks like one of those "Hello from le Mans!" postcards or something.
However, both of these definitely deserve a full critique:
Bram: I like the contrast between the green background, and the red car (LOL Japanrot red). The car is sharp, and angle gives just the slightest hint at the flared arches fore and aft on the car. I see a bit of a reflection in the left mirror, but none on the right one, strangely. Also, is that wafer type silhouette on the bottom of the car the gastank? if so, kudos, I likes it. Good work. Solid photo. But I'll end off with the comment that it just wasn't quite at the level I'd expect of a final round in a tourney.
NTX: ntx....ntx....where do i even start? First off, the BMW M3 GTR has got to be my favourite GT car efar. it's also very photogenic, with just about any angle looking godlike. Next, we have the composition. Solid here too. The only thing out is that it looks like ya juuuust missed that thar apex (i think that's an apex anyway, but I know neither the corner, nor the track). Woulda been nice to see it nailed. Then, and I don't think the rules permitted you to even fix this, there are a few contrast induced jaggies along the checkered bodywork, and a not-so-great shadow which covers the "Original BMW parts" text.
However, what really makes this photo is the "photograph" style. it looks, like I said, like a "Hello from le Mans!" postcard. Phantasmal.
