I know what it's like to arrive at Hive without anyone to guide you and how overwhelming it can be at first. Take it easy and learn little by little. Oh, and don't hesitate to ask any questions!
As for specific recommendations for future posts of your drawings, although they are already in the beginner's guide, I would highlight two in particular:

• Always mention your sources of inspiration. If you copy a drawing from a website, include a link so that credit can be given to its true author.
• It's best to show the step-by-step process so that people can see how the drawings were created.

Recommended communities where you can see how other artists do it: The Anime Realm and YAF - Young Art Fair.
