Interesting compositeSaturn is pretty involved albeit with many positive links which is usually not favorable but given that the composite descendant is ruled by saturn it's can be a godo thing depending how each individual reacts to saturn.
I'm not a big fan of venus square uranus especially with uranus in the 5th house of romance.
That seems to suggest erratic love and sex.
Mars conjunct moon makes for a very intense pairing as does saturn and pluto.
It seems like there might just be too much intensity for it to work on a long term basis.
