As the jam suggests, bro needs some ideas for his future work. I will attempt to share my recommendations and maybe not only towards him.
Let me begin:
- blogs - reflexions about your ideas and plans. Describe concepts and or show drawings of your works. You can also create lore surrounding your works.
- maps - how about trying something harder, like build your map on older mc versions: 1.0.0 or 1.6 for a challenge.
- skins - your skins are simple, yet try to improve your style, add more details, shading, use a specific pallette.
- share your building ideas, like walls, floors or even gardens.

I hope those things would be helpful
