Hi Dave, Desperately trying to a big catch up on comments!
Over - Overgrown for me, it was a bit of a toss up btwn that and the tree lined path but I think that might be better with some leaves on the trees
Age - Two good ones but the grumpy man did make me laugh. He looks really cheesed off about something
Sharp - I like the teasel shot best for this theme. Nice colours and reflection but I would have liked to have all the teasel head in the shot
Guard - Good choice for guard and I like the mono version best, not keen on the pic bg in the colour image
Thick - Another good one and it made me laugh too
