Yeah i was gonna mention that tagging people when I saw my notification that you tagged me and 70 others. Gotta be careful with tagging, and the subjects as well.
I'd say look for communities like created/hive-158694
or created/hive-156509 for posting art.
I found them by searching the art tag, and finding the communities many of them were posted in.
There is also one called Information war, which would be best for political postings such as the charter of rights post you made. created/hive-110786

Introduce yourself to each community, if you're on peakd, use the cross post option to post a single post to other similar communities, with out creating duplicate posts on your main page.
Then most of all, talk to ppl, comment on their posts, and ask advice! People love engagement here, and tend to steer clear of those asking for votes and to please look at my post. Let it happen naturally like making friends. Share some love for others posts, and you can bet they will already be checking out your page.

Other than that, just don't give up. The beginning is the hardest part, but just be consistent, and things will start opening up to you.
