I'm just a newbie too.
And I am a bit lazy on posting my reviews.
I suggest you follow other picky users on IG and see how they do stuffs, like what they include on their reviews, how they take photos, what kind of photos do they post, it helped a bit on my part, it gave me ideas on what I should and not include on my reviews, and gave me ideas like #tetristuesday, #texturethursdays and the likes, I'm just not posting much, lol.
