I'm not a huge fan of the "moan" sound in names, so I can't really get on board with this. Pomme is a cute NN, and I guess it's not bad as a MN. CeliaPomona is nice.
I think it's quite nice. Not the greatest name in the world, but it's still okay. CeliaPomona doesn't really go if you ask me. The a's at the end clash a bit.
