Hi Graham
Joining a little late to this conversation.
Re the first picture. I'd like to see the contrast somewhere in the middle between your edit and Andre's. For me it lacks a little detail. Also, on the upper left side the plate shows some bubbles on the surface. I'd would remove those since they are not pleasant to the eye.
Well done with the flame =)
It's nice to see someone posting images about food, which is something I work on frequently.
