A very small thing. The c570 at the top looks crooked. It might work better if you lined it up parallel with the edge of the grey paint above it.
Good eye, but the number is cocked like it is for a reason that occurred to me since the previous version, so that the number is perfectly horizontal when the sails are fully closed,
the "default" configuration.
Now, it may turn out that aligning the number with the edge of the gray paint is preferable to having it perfectly horizontal with the sails closed, but I'm not going to make that determination without seeing both options.
