Hey welcome to Steemit, the only way to increase your resource credits is to power up more Steem, then you will be able to post and interact a bit more, so keep posting :) Your art is amazing so I included this post in my weekly curation Ocean of Art!

I delegated you 50 steem power for now so you should have enough to do plenty of comments/posts per day if you choose to, I'll leave it with you for a bit until you have built up enough to cover your own :)
