Hows my budget?

Just moved from a TC of “Afford rent and save a little but focus on upping tc” to “okay bud, time to start thinking about the future. (and keep tryna up the TC).” So Im budgeting things out now. After 1500 monthly contribution to 401k, my monthly take home is going to be $8000 a month after taxes. Current rent, subscriptions, muni, living expenses (not food) and gym is $3000 a month, car is paid off so no car payment. Leaves about $5000 to play with. Right now Im thinking 1000 a month into a 2% interest savings, 2500 in ETFs. Once I have 3 months of income in savings Ill start putting $3000 into ETF’s and $500 in savings. Plus the stocks I get vesting from work = additional 37500 a year. This leaves me 1500 a month for personal spending, and anything I dont use Ill just roll into savings. And when it comes time to buy a house Ill liquify some of my holdings for that. Basically of my 210k income, at the end of the year Ill have maxed 401k, 12,000 to savings and ~70k into stock portfolio. Is this good? should I be saving way more? Should I be doing something else with my money? Would you do anything different? Anything I can do to not get slaughtered by taxes? My biggest concern is it taking forever to save up a downpayment on a house or rental property and getting reamed by taxes.
