Progress Report - Backyard Berries

This is the piece I started yesterday.  It's a 15" x 22" half sheet of watercolour paper, and I'm enjoying the process.  How it will turn out I'm not sure - I started with some pretty dark values and it's just getting darker.  One of my biggest trouble areas is keeping good contrast between light and dark values, and while the leaves at right and left are light, I'm not sure if it will be enough.  Time to step back, take a break, come back with a fresh eye to see what I'm not seeing when my face is inches away working on the painting.
