The funny thing of your pic is ... when you mirror it, it looks a little like the Planet Coaster logo ...

And how about a little change in the Sandbox Mode

Winter Sandbox is a nice idea, but I don't want to encourage continued Terrain Paint separation. Disneyland is in a deciduous / desert area of California, but there is a HUGE snowy mountain in the middle of the park! Winter Sandbox is great as long as Snow Terrain Paint (and Sand/Red Rock, and Asphalt for that matter) are available in all sandboxes. At least Deciduous should have a wide variety of terrain paints since it is in many ways the default or generic sandbox.
