In your birth chart we see that the boy is born under Magha Nakshatra 3rd charan, and the Girl is born under Rohini Nakshatra 2nd charan. As there is no Nadi Paad vedha, it means that Nadi dosha gets canceled. You can add 8 score of Guna Milan to 11, which is your Guna Milan score. Also, there is friendship in the D9 chart, which is good as it cancels Gana dosha. Therefore, the final effective score after checking dosha cancellation will be 11 + 8 + 6 = 25 out of 36, which is above 18, making you eligible for marriage.
