Some Saving Advice Wanted

Hey, just looking for some advice.

I'm 21 years old, just graduating from college luckily with $0 debt....thank you scholarships.

Current value:

Mutual funds: 12k
Savings: 5k
Debt: 0

I'm looking at expanding into roth IRA, but being self-employed no 401k will be available. Is there anything else I should look at investing in?

Thanks a lot...
