Is this a good extraction?

Got a moka pot for Christmas and have recently tried to master the art of the brew. I felt like this was my best testing brew yet, but I wanted to check wether my extraction looked good, or wether you can see anyy glaring issues.

I used boiler water and let it go on medium heat for 6-8 minutes before the coffe pushed through. I then lowered the heat to the lowest setting. Finally cooling it down with cold water when I heard/saw the sputtering.
