I love the colors and the adjustments you did on the fill. No problem understanding this map at a glance or being able to enjoy the detail.

I will comment on the scale bar, whatever scale you decide it should be, your scale bar needs to have a reasonable increment for it. i.e. you label the size at 500, but the bar has 8 segments. This means each segment is 62.5 miles. Each segment should be an even number, like 10, 20, 25, 50, etc.
