There are way too many crossings. Remember: one crossing at the middle of each edge, no more, no less. It’s not a problem though because you just have to slash them with a wall (meaning there really is no edge there). It often more convenient to put an edge and slash it in order to have a well balanced graph like yours, rather than having a hollow graph that doesn’t stand firm on its legs.
You missed a double crossing in the lower right part where there is the little wiggle.
Don’t hesitate to split a large zone (like the red one at the upper left corner) into 2 vertices, connected by a (...)
