We'll also suggest #vybranium or #vyb, #proofofbrain, #arttalk, #artclub, and maybe check #sketchbook community and other communities: check their rules, and for tags as well.
You should be able to get way more exposure for your artwork, it's very beautiful @mammanneke!!
You need to stop double posting!!! Only post each post one time, and you can add these tags or the ones Britt suggested by clicking on the 3 dots and editing your post, just add some more. You can use up to 10, and you definitely need more exposure. Also, if you are on Discord, and want some information and learning about Hive, please come into The Terminal and we'll get you going. Here is an open invitation:
