I feel the same way too dude I feel like people don't care about what i post maybe try posting something that'd grab their attention i guess?

I tried everything yet nothing works, it's the same result for all my other social medias. I pick up more dust than engaging with new followers

1. Human characters aren't that popular on this site
2. Sfw artists tend to struggle more overall
3. You seem to only do sfw male drawings.

I like to try new things, sadly I'm strictly a SFW character artist

Plus, it's the same result on my Deviant Art acc. and Instagram, and Twitter, and Art Station and pretty much everywhere I have a social media

Well from what I see in your gallery, you mainly do Ocs and fanart of niche characters and franchises. If you want attention, you gotta do characters people wanna see. Characters people love and know to no end. Think of it as doing a remix of a popular song, then uploading your own. People come for the trends and popular stuff, an stay for the originals because they're interested in what you can do. Instead of endless sonic fanart, do undertale or deltarune characters, some smash bros art, maybe some friday night funkin stuff, popular shit. You gotta draw the crowd in before you can keep them around. If that makes sense.

I do like stuff like Monster Hunter, Smash Bros, Guilty Gear, Crash Bandicoot, Spyro, Sonic, The Legend of Zelda, Pokemon and a huge Etc.

I can make a fan art of those at some point

all I can say is look at the artwork you fave and engage with.

I mean.... well crap, I barely fav and comment on stuff that has to do with character design

That's totally my fault it seems
