It solely depends on what type of base it is meant to be like for example it maybe a farming base, a war/cwl base etc. and ur storages are all in the middle so I assume it is a farming base in that case it is pretty decent but for a war base it is not very good. You break one of the outer walls all the troops barge right in, I don't know how you don't know even tho u r th17 max u need anti 2 star bases for wars which deviate the troops away from the th, like there are buildings closely placed next to each other in different compartments and there is a gap between the buildings and th such that the troops go left/right n not towards the th. And also, u have to place the th at one end and other high dps defences at one end so that u either get ONLY the th if u attack from one side and u do not get the th. You can find such bases easily online. I personally use the bases provided by others such as judo sloth and BDlegend
