I'd rather see the "Starz" (which is the team name) under the name of the gym (which is Columbus Gymnastics Academy) instead of between it. A number of the coaches like this design best, but it is a bit "busy" for me.
For the "people" in the logo: The middle person needs to have both legs straight. The left person needs to have straight legs. The curved back is fine, but the legs need to be straight.
#45 - white around Columbus is good. As you are looking at the logo: right figure - front toe more pointed center figure - front toe more pointed left figure - keep the curve in the body that you had before BUT ADD straight legs with feet together and pointed toes
