dome to arch connection

[stefc]

Hi, new to the forum. I come here with a specific question about my build (work in progress). This has been a challenging project with a lot of learnings. I would like to get any advice on the next steps in my build. Connecting the dome with the arch. I opted to keep arch structurally sound but this means that the dome pieces that connect dome and arch will "hang" like in a void. Of course they will be cut to touch the arch well and they will be held in place by the additional ring layers but still Im not sure if this is structurally sound. Any advice/experience with this would be appreciated

Have a nice day!
