At HIVE we don't have many rules. It depends on the individual what rules are applied. Only the blockchain coded rules are hard rules :)
I truly love your work and usually, such work is rewarded (much) more in our HIVE community, as you may have seen from other users posts and contributions.
The larger rewards are generally handed out by curator teams. Many of these teams are looking for added value and the work someone is putting into a post. They usually look for new material. Not saying older material is not liked, but generally, this older material needs more (new) value added to the shared content. I think, in the end, curator teams like to see active involvement in the community, with some good work done for the post for them to hand out dollars to 10s of dollars of rewards. I know that are the soft rules I apply with my vote account controlling an up to 6$ vote. My suggestion is to add more stories (of any kind) around your shares.
In the end, it is up to you what you do and how you plan to continue :)
