Hmm, sideways pics, sorry!!
I've been bitten by the bonsai bug too. Did a 1 day course with Greenwood bonsai nr Nottingham in January and I have foubd myself passing sapling and shrubs in so many places thinking ooo that looks like it might make a bonsai....bought a couple of evergreens to have a go at and currently growing on some field grown deciduous babies to have a go at in a couple of years,some before and after pics below the first 2 are the tree from the course
