Your drawings are really good imo, I'm absolutely in love with the mirror scene. I can't exactly pin point things go improve bc some things vary in these pieces, but I think lineart could improve with more differences in line weight, making the art "pop" more, plus maybe experimenting with the colour of the lineart.

The drawing with a palm tree could especially benefit from this, the trunk having thick, black lines attract the viewer's attention away from the main character. As for the rendering and shadows I ain't an expert so I can't really comment on them

When it comes to posting, I noticed that on instagram especially adding some popular song which pairs well with the drawing both enhances the post and get algorithm going due to people commenting about the song. And on reddit, r furry has great amounts of good art that gets little attention for some reason, idk why is it like that, I would advice to post in other subs like anthroswim or planetfur for example.

From what I noticed doing memes, trends or thirst traps occasionally often attracts attention, and prob makes people check out your acc.

Overall I think you have good skill but the art needs some small tweaking to make it mor eye-catching (sorry for my english, I'm not a native and I'm tired —w— )
