What on earth are you trying to do? To me, someone is just drawing 'pretty pictures' and it could not be considered correct heraldry. Just from the image alone, it isn't proper heraldry at all for the following reasons...
1. The arms are shown on a lozenge, so they must be female.
2. Females don't have crests except in very special circumstances - i.e., the arms are for a Scottish clan chieftain when they would have a shield, helm and motto.
3. Women don't display any mantling (if that's what it is supposed to be) because they don't have helms to which it is attached, unless as a Scottish clan chieftain.
4. If the lady holds a peerage title, then she is entitled to display the coronet applicable to her rank above the arms. The one shown there isn't a coronet of peerage rank it is a standard 'charge'.
5. Supporters are supposed to support the shield - the horse supporters don't appear to be touching the arms with any of their hooves.
6. The lady would not be entitled to have supporters except in exceptional circumstances -holder of a peerage title; the holder of a Dame Grand Cross of most orders of chivalry, etc.
7. With your attempt at blazoning you should blazon the shield first, then you blazon the crest.
8. If they were male arms, besides their being placed on a shield, you don't have a crest without its appropriate helm.
9. IF there was a crest sitting on top of a Helm, the wording of the crest blazon would be either 'from ...' or 'issuant from ...'. On some badly depicted crests the crest object has quite often been incorrectly drawn by showing the crest object sitting on the torse/wreath that usually accompanies mantling.
10. The two partitions in the base of the achievement (coat of arms) are incorrect as they are not shown in their entirety so it would be impossible to guess what else might be there.
For whom are these arms supposed to be?
What exactly are you after - just a blazon for the crest, or for the whole caboodle ?
