Defo move the bolt to the front of the fork crown. It's going to catch on everything from steps (eg in/out of shed) to leaves and twigs like that. If that's not possible, you could remove the flap – but then there'd be no point having Longboards.
As for the colour, yeah, it's not different enough to be a contrast but at the same time it doesn't match. Whether that really matters is up to you though.
