I started my art account with 7 followers (I forgot to take a photo). I am a college student who makes art on the side for fun. I've been posting artwork now daily for a week. Some of them were old work and now I've been making new pieces. I went up to 25 followers in 5 days.
I have now been posting new digital drawings, videos, and stories. I found that increasing my number of hashtags really helped me as well as following the followers of large art accounts.
It has been a full week now, and I have increased to 44 followers which is exciting! I will update this post once it's been two weeks.
