The best thing you can do is vote. Vote your voting power down to about 90% each day and it will be refilled by the next day. If you do that and vote on posts you like you will grow your account by getting rewards for using your voting.

If you delegate your Hive Power to someone or a group... they will use your VP added to their own. You can get rewards for doing that... but you have such little HP that it would take longer to grow that way than just voting yourself.

Plus, if you delegate your HP it doesn't affect your own voting power consumption... it just lessens the value of your vote.

If you join the NFT Showroom discord you can get started in there. The link is in the weekly curation posts. You can mint your artwork there for sure. There is a frequently asked questions help room in there that answers a lot of the NFT Showroom questions. I think there are a few video tutorials in there and some really cool and helpful people in the general chat very willing to help out. NFT Showroom is the best place to mint as far as cost goes. I have a feeling your stuff would sell probably better than mine over there too!

I hope those answers help out!
