Acute angle routes in PCB
Old timers might grumble about "etchant traps" ... acute angles can hold acid (well, FeCl) long enough to eat through the track - or not, depending on who makes the PCB for you. Consult with them if you are worried.

But I was downvoted for pointing that out in a previous answer, so at least somebody thinks that's no longer a problem. 

As far as the signal speed on that trace - nothing to worry about.
