Bicentennial Rock Garden

I took Kanoe for a walk at Liliuokalani Park this afternoon, hoping to catch some sun before the big storm heading this way. We found a nice spot in the shade next to the Bicentennial Rock Garden and spent a relaxing couple hours taking in the sights and sounds, where I drew to my heart's content. I took along my new travel watercolors to give this drawing a wash before heading home. I'm trying to decide whether or not to work on it some more. What do you think?
