Buy VOO by Jan 20, 2036.

Hello, as stated in the title I recently opened a Roth IRA with Robinhood. I went back on how to split the allocations for a while. I finally landed on 40% VOO, 30% VTI, 20% VXUS, 10% QQQ. Aiming to balance for long term growth and thats not overdepedent on tech, US market, ect... I have a good amount of experience investing but definitely don't know it all. Any advice or breakdowns would be appreciated.
