A park for my sculptures - Choosing what to put in it in the next years (A "Steemit" sculpture too, perhaps?)

I have been offered to make some very large sculpture to create a "Land Art Space" with my artworks. I don't know if this project will become real, but I'm working to sketch and design the first of these huge sculptures/installations.

I drew a lot of sketches already, but I'm also checking some of my old sculptures to see if some of them could be a good subject. 

Here are these old artworks:

What do you think about them?

Well, I could also put in this "Art Park" a big Steemit logo. But I think it will be better to wait the redesign of Steem/Steemit that is scheduled in the Roadmap ;)
