I don't fully agree, this is almost what a Seraphim looks like....
They are perfect and a little higher than us, but fellow servants to us worshipping God alone. The Angels who have fallen from their place in Heaven have already done so 1/3 of them with satan and stand condemned already. The remaining will are with God, some do come to earth like man, in human like form but are Angels with a message to people.
Angels were not born on Earth, as far as we know angels are not born, angels are not of any earthly chemical or mineral. They are not people.
Do they have a thinking and feeling process, yes they do.
Some of them are sinless the ones that committed sins or the ones that fell and more cast down to earth or held in chains of darkness until judgment, after all God said Lucifer was perfect in all his ways until pride was found in him.
And what do angels really look like in their natural form?
No. They APPEAR in human form. But are certainly not in fact their truest form. Very frightening. They do it as a kindness and comforting measure out of benevolence
