Heya Redwookie, welcome to The Photo Forum.
You are using your camera well, working with available light only and using your aperture setting to create some nice DOF (depth of field) with blurred backgrounds.
Compositionwise I find the first photo a bit too centred, which no longer applies to the second, though the crop on the caroussel horse head is a bit tight and I would have liked to also see its ears inside your frame.
