I am very new to this and have been working on how to blazon and so far I have:

Per fess Vert and barry wavy of six Argent and Azure, in chief a naval crown Or issuant a mast and sail Or between two stag’s attires of the same. For a crest, issuant from a coronet Or a stag’s head Or attired of the same. Supporters dexter a lion rampant Or armed Argent

and langued Gules, sinister a hippocampus Argent crined, finned, unguled and queued Azure; compartment rocks issuant from the sea.

I’m pretty confident that I have the overall idea correct but I am also pretty confident the details are not.

I’d appreciate any feedback/advice
