Hey there @mindhawk.
Your query about curation rewards is one that many new Steemians have.
I do have some good news, though. It looks like you have been earning some small curation rewards along the way! You can check on your curation rewards by visiting SteemNow and looking at the section about curation rewards.
The unfortunate part is that since your STEEM power is low, it will be a while before you notice significant curation rewards. Curation rewards depend on the STEEM power of the accounts which vote on a post. Therefore, you should continue what you're doing and focus on growing your account, networking with others, and building up some followers. As your account grows and you continue to vote, the curation rewards will follow!
I hope this helps.
