Deciding to start my investing journey. 50% in QQQM and 50% in VXUS

I am 32. Going to put money in every two weeks. Goal is to be able to retire comfortably in 25 years. Wanted to put money into tech, which is why I chose QQQM and wanted some diversity so I chose VXUS. Originally was going to do SCHD and VOO with QQQM but chose these instead. What is everyone’s thoughts?
