A train post where OP actually tried signalling it on his own first AND is holding a signal to clearly show the blocks. Great!

Signalling looks good, it's secure from any deadlocks. If you want to raise the throughput a little you can replace the chain signals with regular signals in the places where the trains have cleared all crossing paths - that will allow new trains to move in slightly quicker while still keeping the intersection safe. It's not a big deal at all though, so you can easily keep it as you've made it. And if you happen to get queues on the straight paths the extra chain signals does help keeping the intersection free, depending on the length of your trains.

Really nice work from a person who's new to trains! :)
