+1 They don't look too bad, just not quite finished
Get your self a set of jewelers files to smooth out the insides. Depending on the bits you have for your Dremel you could maybe get a bit closer with that before going to the file work, let the cutter do it's job- don't push too hard or let it chatter. Slow and steady wins the race here, if get in a hurry you risk removing too much.
