not to bad, but your friend needs a polarizer and find a better time of day and location to shoot.
I'm not trying to sound like an ass but those aren't worth $$ in my eyes...and I've done enough stuff on my own that I wouldn't even pay for. Maybe it's just because I'm highly critical of photos (mine or anyone's for that matter). I'm willing to do photoshoots of cars free of charge if they fit what I'm looking for (which isn't asking a whole hell of a lot). It took me awhile to feel comfortable with my 300d (building up my lenses and skill level).
Nice start with the D70 though.
