I agree - on the whole not bad,
#1 - They're looking at the main tog, its needs eye contact
#2 - I like, but it looks as though there are some jpeg compression issues going on with the version you've posted here
#3 I'm not a selective colouriong fan - I'd like to see the original.
#4 I like - I think you were asking too much of the lens though
#5 I like this, but it would be better if he had a less shiny head
#6 Agree with above
#7 If you must selective colour you need to be subtle, pick just one colour or item and have the rest in black and white - like the red/purply flowers for example. I'd like to see the original of this but you also have eye contact issues
Cheers
