Another conference, another doodle...or four

I was at a conference all day today, so I put my "brain's listening, hands are drawing" approach into action again, and occupied my hands with a watercolour postcard pad and a 0.05 nib pens.
This is the result:

 Introduction and First Keynote Speaker

Session on "Professional Knowledge and Skills Base"

Parallel session on a CPD23 experience

Final session keynote - it started as nothing and ended up suggesting itself as a bat

All of these postcards are rehomed or on offer to people - some of them to the people whose sessions I drew them in. I hope they're not offended, but it really is something I do to keep my hands busy, while my brain is occupied listening!
