Those look great! I (kinda) like the appearance of my shell rock...maybe might go with a wee bit more cement next time.
Remember when making MMLR, part of the goal to to have as much surface space and pores/opening as possible/practical. The overall idea is creating a haven for massive amounts of happy bacteria

3:1 concrete to sand? or sand to concrete? (or whatever you used with the concrete?

)

3 parts "stuff" to 1 part concrete.

I use 3 parts coarse salt and 1 part cement. Very light and porous.

The best part of DIY rock is the shapes of BIG (huge) custom shaped pieces you can make to hide over flows or power heads. take you time and design your dream rock shapes. use playground sand as a form...
then...
get a garbage can put it outside and fill it with the hose to cure the BIG pieces. you need to do it outside b/c you need to change the water every few days for several weeks (many weeks for thick pieces)
I made awesome pieces last fall that cover my overflow but dont take up much tank space
