What am I doing wrong? 40YO looking to keeping earning until 70.

I have two accounts - a Brokerage for which I have FXNAX 25% and VT 75% and a Roth which is FXAIX 80% and FSPSX 20%. Am I missing something vital here? I did a ton of research when I initially invested but now don't remember why I made these choices - going to go back through all the documents/threads but figured I'd ask here as well!
