The small air bubbles wont hurt. If you want, you could sand the fillets fair and then put a coat of thick epoxy over them to cover the bubbles. I have also noticed that thick in the cup and thick on the hull are different. I test by dipping a glob on the mix stick and holding it up. If it stays on there, it's thick enough. Even then it will still try to run a little but any thicker and it's harder to put on. I have also successfully added dry sawdust to the top of the fillet while it's wet. This essentially thickens the surface a little. Don't worry, there's plenty of epoxy in there.

Or maybe geraniums would look nice...:)
