The ashtkoot guna milan score is 24,5 which is higher than 18 that is required for marriage. There is Gana dosha as the girl belongs to Rakshasa Gana her Nakshatra being Jyeshtha Nakshatra.
On the Manglik front we see that in the birth chart of Boy Mars is placed in the seventh house from the lagna while in the Moon chart Mars is placed in fourth house from the Moon. Hence Boy is Mangalik from the Birth Chart and also Chandra Mangalik from the Moon Chart.
In the birth chart of Girl Mars is placed in the eleventh house from the lagna while in the Moon chart Mars is placed in eighth house from the Moon. Hence Girl is not Mangalik from the Birth Chart but Chandra Mangalik from the Moon Chart.
As both charts have Mangal dosha they are compatible on the mangalik front.
The individual horoscope of the boy and the Girl are both weak. 7th house is the prime house of marriage in the birth chart. the strength of the 7th house is prime for marital happiness. In the horoscope of the Boy we see there is Saturn conjoined with Mars. This is never good combination and where Saturn and Mars conjoin they severely affect the significance of that house.
In the horoscope of the Girl we see there is Rahu in the 7th house. Rahu in the horoscope placed in the 7th house brings obstacles before and also after marriage. Therefore both horoscopes are average on the marital front.
Therefore despite your Good Guna milan score I feel the overall Horoscope compatibility is average only.
