sorry, really dont want to be rude but I dont like any of them. here is where try to soften the blow part comes in where I try to explain why instead of just leaving it with a negative comment.
The subjects you used were all beautiful exotic cars, yet the pictures are boring. I think what "juice" above was trying to say was, the R8 is a sexy sexy car and a gas cap, regardless if it is wrapped in carbon fiber or 24K gold is not exciting. If you had several pictures of the R8 and that happened to be one of them, then ok. But for 1 single shot to display as the R8....doesn't really show anything off. as for The carrera, I wish there was more in the picture. like if you were to have used a wide angle lens to be able to focus on the badge but still brought in some of the sexiness this car has to offer. (maybe you dont have several lenses to chose from though. (I dont make enough money to have that option so it makes sense if it was just a lack of lens options. Something about the 3rd picture that I dont like, but I cant figure out what it is. Might be that it simply cut off the left side of the car or maybe its a tad dark? I dont know, just doesn't "speak" to me. really not trying to be mean about it at all, in fact let me clarify that right now....not trying to be mean about it....lol
Its easy to critique, another to be able to do. Keep on keeping on!
