Need help with my Vanguard account. Not sure what to do and need some advice.

AI have 160K in a TIRA w/ 50k in both VOO & VTI and 30k in both VEA & VXUS. Also a 15k inherited IRA split between VOO & VTI. Is this wise or monotonous? I would be grateful for any advice and what I could possibly do better. Thank you
