My pleasure to help Steemians.

Are there any other ways I could promote my writing?

The short path is to pay bidbots for upvotes, but it cost money and is short view IMHO
Being successful on Steem is a long run. My advises are:

• write on what you like and know
• interact with people on your post and on theirs to extend your network
• stay committed

I wish you all the best on Steem

BTW, feel free to vote for me as a witness if you like my work at promoting your posts.
