Grow a presence here if you haven't already by joining art/animation collabs, hop on forums with other artists/animators to share experiences or even an art dump thread, or going back to collabs, start one yourself so Tom can showcase it for you! There isn't an algorithm and it's all about finding your audience through true connections with the community.
When it comes to getting on the front page, remember that there are amazingly talented artists I know personally who know they are good at what they do who won't be on the front page anytime soon. Don't put yourself down because you won't get to that point anytime soon, it took me a good few years until recently I earned that front page on a few of my pieces. Worry more about what you enjoy creating and finding a community who will love to hop on what ever it is you're into for the moment.

I think slow follower growth on NG is pretty normal. I'm, personally, mostly just a lurker here to see cool art and movies, but I think in general the "value-add" for twitter isn't getting an audience, it's getting a friend group with fellow artists.
Maybe try joining, or even better running, a collab, hang out on the forums a bit, participate in an art jam or concert. There aren't really a lot of discovery tools here (though there is the newly introduced Takeover Tuesday), because this isn't instagram or w/e.
Anyway, I'm (obviously) not an artists or anything of the sort, so take this all with a grain of salt. Your art is super cute though, so I hope you have fun doing it, and don't worry too much about followers and stats and such.
Good Luck :D

I don’t know much about how to use Newgrounds outside of posting so I was wondering where are the collab things at it here? Also art jams, Takeover Tuesday and concerts are something completely new to me but sounds interesting :0
Also thank you so much and yeah I am, I just wish I knew how this website worked a bit more; it’s a bit confusing despite being here for 2 years haha
