With estimated expenses that low and your income so high, you look fine to me. I wouldn't worry about it. Unexpected expenses and desires can usually be delayed if needed, and you have more than one income stream. If you lost your job your side gigs would almost pay for everything while you looked for a new job. Plus, you can increase your emergency fund rapidly over the next few months.
I would personally be sure to have a credit card for true emergencies, but also for regular use. If you don't have one, but are responsible to ALWAYS pay it off on time so you pay no interest, I would get one before moving out. (Discover gives card to people with no credit- I'd find a friend with one, and use their referral link- $50 per person bonus that way)
Just be careful to pay attention to lifestyle inflation. You have a good income in a low cost area- you are in a great situation, with far more in savings than most Americans in your position would have.. I would not completely stop the 401k contributions, as I cannot really see an emergency where you would need so much cash at one. Maybe put them back up to 20% or 30%?
And look into putting $5500 into a traditional (or roth if it makes sense) IRA- the fees are usually lower, and it gives you more control than a 401k. Plus, you can max both if you want to.. the usual hierarchy is this: 401k to the match, then max the IRA, lastly max your 401k. If you prefer less interaction the 401k isn't a bad thing, just usually not better than an IRA. (If you max both, great!)
Best of luck!
