Capricorn on the inside, Cancer on the way in.
Your sun in Capricorn (earth, cardinal) is the engine — what grounds at the centre, what starts when you are at home in yourself. Your Cancer rising (water, cardinal, ruled by Moon) is the door — the way you arrive in a room, the first read the world takes of you, the body you walk in.
Strangers tend to assume you are sensitive and tidal — that is the Cancer arriving first. Then they get to know you and discover the Capricorn earth underneath, which can be a layered second read — they have to update their first impression.
Reads as Cancer until you trust them; then Capricorn comes through. The cardinal-cardinal mix means you consistently starts.
