Leading lines

First day back to Digital Photography class this morning. It was pouring with rain when I started out but it had dried up by the time I got to College. The tutor took us to Ashbrook Garden Centre in Arbroath with instructions to consider rule of thirds, leading lines, composition, using manual, etc. etc. - quite a challenge. I took lots of shots of flowers, trees, statues, but really I think this shot of the roof of a glass greenhouse is interesting as the lines are clearly leading somewhere lol!
