African Violets like to be pot bound. It looks pretty healthy to me, but it looks like the soil is really wet under the garnish, whatever it is they have on it. They are prone to rot, like to be watered from the bottom, and like bright indirect light. When you do repot, they like a light textured soil, so add a lot of perilte. Years ago I was told not to repot until they were developing a "neck". When that happens, trim off one or two outer layers of leaves and repot one size bigger, placing the neck back down to soil level, Hope this helps, I had some of mine for 20 years and they are still going strong.
