Hot hot hot

After my last rather grumpy and ugly entry, I thought I would find a sunnier image to post today. I haven't had time to paint or sketch so this is an old one, which lives with my sister Gillian in Texas - and it's appropriate - at last summer has returned to Joburg and it is hot, as it should be at this time of year. Although this painting has many faults which are glaringly obvious to me now, I feel I was at the time making headway with my watercolours - getting freer, cleaner (still some mud here) and fresher... and then I stopped... why? Now I'm back to square..if not 1, then 2 or 3. I've wandered off into other mediums and I think with each one I reach a certain stage, and then switch tack, so never actually become totally adept at any of them. I'm feeling the pull of watercolours again, and am wondering whether to commit to a year or two of just those... but then my expensive oil paints may dry out and I'll lose whatever familiarity I've built up with them. Can one juggle a few techniques at the same time (I have to use pen, ink and graphite for daily-ish sketching too), or should you stay true to one until you're quite on top of it? Any advice appreciated!
