Well don't be nervous about that, be excited! The community here is pretty awesome. And there are some great places to get quality feedback apart from steemit too. My first 2 chapters are my originals, but the good people over at the MSP writer's workshop on Discord are awesome when it comes to promoting each other's work and quality peer editing. If you want, come find me at the fiction-workshop channel. @rhondak has a great info post about the channel on discord at:

I recommend all new authors (which includes myself) to head there for awesome support! Thank you for taking the time to read my work! It continues to give me motivation to keep going!
