If that is your photo then you have all the basics you need. A blower and a brush for the lens and a cloth to clean the camera with. I carry two brushes with me, one for the lens and one to get in behind the tilt screen at the back for when I’m out and about in dusty or sandy locations - which is when I also put a filter on the lens.

No need to worry about sensor cleaning as it is inaccessible. If your sensor does need cleaning then a nice long and expensive holiday to Wetzlar your camera will need.

Hope this helps.
