Anacortes painting

I thought I wanted to see Plein Air WA's show at Scott-Milo Gallery in Anacortes, but didn't think about it was closed on Sundays. I should have remembered the fact. Instead, I painted on R Ave. looking toward Mt. Baker.
It was hot day so I didn't take my sun glass off - mistake #1. And again, the color&value shift of mountains based on distance isn't right. I need more practice about it.
