Help on Current Portfolio

Hello! I’m a 21 year old college student, set to graduate soon! My oldest brother got me into investing and I’ve already made a few mistakes and took my initial $100 investment into individual stocks out after only a month. I did some research for my current portfolio idea. I’ve wanted a portfolio for moderate risk tolerance and I plan to invest and forget, so here’s what I cooked up! I’m open to all suggestions/ideas!

Taxable: 70% VTI, 15% VXUS, 10% SMH, 5% Fun

Roth IRA: 50% FZROX, 25% SPMO, 25% AVUV

There’s been so many ETFs (QQQM,SCHG,VUG,VGT,VOO, etc) that I’ve read about so I want to set a foundation now so I can start forgetting to avoid any emotional thinking.

Thank you so much!
