For reference, I used a small gouache sketch I did a while ago from a photo I took at Sunken Meadow State Park a few years back. I'd always wanted to do something larger, lol.... this isn't larger, it's about the same size... I guess my next step will be to go larger, I kind of like the color palette, something different.
