A good set of shots Steve,
I think I would have taken a few liberties in PP with the detritus surrounding the 'mouse thing' (No.2), although I like the arching grass over the top.
... and possibly cloned out the vertical trunks between the two giraffe too (No.1).
Nice 'flow'/wave on the seal/sealion thingy too (No.5).
Probably my favourite is the stag though (No.3).
