190 seems kind of low for PLA. But I suppose some filaments might go lower. The reason why I said it seems too hot is that when it is too hot it will cause stringing and drooping. You clearly have stringing. Drooping (due to temps being too high) is most commonly seen in bridging, but can also be seen in overhangs. Keep in mind that if the temp is too low, it will cause the layers to not adhere to each other. You have to find a happy medium.
