Some overlap stay on course or pivot?

I’m somewhat new to investing. I have a 401k through work, Roth IRA with only VTI. I plan on maxing this out this year.

I also have a brokerage account with 4 etf’s

VOO 55%
VXUS 30%
VBR 10%
BND 5%

I know their are tax advantages to the Roth but I can’t guarantee I won’t need money down the line.

Is it okay to keep this arrangement?
