Hi Neville,
i checked out your pictures and i think they are great!
I also think the Canon guy ist mostly being a douche.
Moslty because: i think your processing could be *a little* better. But it's not so much off that it justifies the comment that you've gotten.
I do think however that
- your saturation is too high (if you don't adjust the saturation yourself, it could come from adjusting the contrast which affects saturation as well). the grass looks almost a little radioactive. when you have people in the background (out of focus, in the audience), and they have a pink sweater or something like that, it's always VERY intense pink. look
here, the shirts are VERY red, but especially the orange shoes are glow-in-the-dark-orange, and the red stuff in the background is also very intense.
- your skin tones are a little strange. i suspect that comes from the high saturation as well. it's normal that some people have skin that is more on the orange side, some more on the green side, and some on the pink side. in your picture, this difference is intense. examples:
orange,
orange&pink&green,
green.
i hope my criticism is ok for you, and that it helps.
The job is well done, so you cerntainly don't deserve the comment the Canon guy gave you.
