hi
vedic comptibility score is less 18 out of 36 gunas. analysed for mangal dosha, mangal is strong in fiery sign ( dhanus), but present along with sun and benefic venus.which reduces dosha to some extent.
but its star lord ketu is 7th house which is not suitable for marital compatibility.
compared to your mars boys mars is much stronger.
hence marriage compatibility is weak and you are advised to consult more expereinced astrologers like sri TMR sir on this forum for further guidance
