Ok Darren.... You have asked me to look over your shots and critique them.... First I'd like it to be known, that I'm not a guru when it comes to photography.... I do teach it at high school and I use to teach it at Uni, but for the most part, I am self taught.... And this is what I recommend to everyone...
Now to your pics....
They are all nice shots, but the best ones (for me anyway) are the more abstract ones.... Now we have a little bit of problem with this statement.... Before you take a photo, you must create brief for yourself.... What is the purpose are these shots? Are you after technically interesting shots? Shots for publication? Abstract, creative shots? Happy Snappy's?
To me, most of the shots you have here are the latter.... Nothing wrong with that, but not overly creative.... These sort of shots, with a little tweaking would work well in a 'middle of the road' magazine.... They would not cut it in a mag such as MOTOR or STREET MACHINE, but they'd be fine for show spread in AVWM....
Now this is not a negative criticism of the shots, I'm just pointing out the differences between this work and Luke's stuff.... Luke takes shots more like I do.... Its more abstract, more human, more descriptive, more exhibitable... If there was such a word!

Our sort of stuff appeals on an artistic level.... Its something that you would put on the wall at a gallery and sell as a work of art.... Its not a publishable image for the mainstream, its more a 'coffee table' sort of product....
Some of your shots are working very well.... Take the B&W ones for instance.... You focus on the details more, not the whole car, you are looking at the tail light, the stripe, the pulley, the lines, etc.... The foreground is cropped out and the background is obscured... Some of your shots are getting good arty results, but the bulk of them are only skin deep.... Like VW's, Porkers have lovely lines, fine details and impeccable form, use those factors as points of focus..... In an environment such as a car show, where there is so much going on around you and the landscape is highly active (ie: trees, people, flags, buildings, signs), you need to get closer to your subject and try to minimize the periphery!
I hope this is of some help Darren.... You are well on your way...
