I took mine to LHBS and asked the owner who is a certified beer judge to rate. I was a little bummed. He picked up astringency, which I learned I may be getting by over sparging. I have not been checking my gravity of my final runnings. I learned that you should not let them go below 1.010 or they can include tannins which will make it astringent. Other than that he liked it except said it was out of style being 8%, it would have to be entered as a Belgian specialty ale. Overall if you were judging it he rated at about a 30. This was also due to lack of carbonation. I filled a bottle from the keg and couldn't keep it from foaming. By the time he got it it was pretty flat.
30 is not bad. As for astringency, you may want to look into pH if you don't already. Much easier than tracking the gravity of your running a IMO. I brew something similar o this recipe but I don't add any simple sugar. That will lower your abv and the 3711 has no issues brining this down to 1.004. Mine omens in around 6.5, which I think it perfect.
