All recommendations are welcome. In particular how to vibrate a two part mold without it breaking apart. I did not weigh the mix and water, but i suspect i used too much water. Also added about 2% plasticizer.

Thank you for the advice. Do you really think a toothbrush will work? ^^ I read somewhere that oil spray (you know for pans and stuff) was good, so i tried that and it seemed to work fine, the form slipped pretty easily.
Pam or similar should be fine as a mould release. A YouTuber we watch, Evan and Katelyn, did an experiment testing different vibration methods for concrete, and they found a personal vibrator (yes, that) was the best for smaller projects like this.
