Not to sound too harsh and narky, but please re-read the announcement on the homepage
Pick out 3 or so pics that you want for critique and stick the rest in a gallery with a link to the gallery.
Judging from your pics and what I heard from friends, I don't think I missed out on a whole heap by not going to it.
The carshows usually are a pain when it comes to lighting with fluro lights, etc creating all sorts of hotspots but the car pics you've taken, the exposure seems to be good enough - from what you had to work it.
Composition needs some work. The first pic of the chrome rim feels more like a happy snap than anything. Usually with rims, get down low and make sure the entire rim is in the photo. Create a tighter comp with a portrait than a landscape layout.
The rest of the car pics, it would have been nicer if the entire car was in the pic or at least most of the car.
The pic of the Cadence
model is pretty out of focus. With the
models who are paid to be there (ie. Cadence) take your time and don't rush it.
IMHO, my personal preference would be the GT4 (or celica made to look like a GT4) as it's fairly sharp and I can actually see the whole car.
