Witch is a first normaly I think such ideas as laughable
When you're ready I wouldn't be afraid. You can't let fear stop you. On the other hand make sure your draft is done, and you've done enough editing that you are proud of what you show.
Sometimes comments can be harsh, when readability is low. It takes a while to build a thick skin.
You can try on baen's bar. Look around the slush pile and see what others are doing. Or find some beta readers.
Don't let anything discourage you. Don't be rushed either but conversely, don't hesitate. She who hesitates is lost after all.
Just be brave and be ready. That's all you can do. I'm sure you'll do fine. It took me lots of years, and even some comments asking if english was my second language. Which stung. But finally I created something I'm very proud of. I know you can too.
