Hey @otakshu, welcome to Hive!
A couple tips to get your posts more visibility:
If you subscribe to the On Chain Art community (similar to subreddits): trending/hive-156509 next time you're about to make a post you can direct it to that community at the top of the page. If you check the community out you'll notice the general ways of artists sharing their work here by also adding some text about it, etc, which could help you get more votes.
Another thing is that because of the way rewards work here we get a lot of identity thieves pretending to be others for the rewards, it would help curators a lot if you could verify that this account belongs to you through one of your socials. Even though I know this is you since I invited you, the OCA community would tag you as a verified artist and curators would know their votes are going to the right person!

Here's a link to the OCD discord if you ever have more questions about the platform: https://discord.gg/p7dHs3
