(In properly designed gears for minimal noise and backlash, etc., there is a complicated formula to determine where to position the pitch circle and how to contour the teeth accordingly-see answer.) You can just put it halfway between for your purposes. The pitch circle is somewhere between the tips and bases of the gears. The dimension that should be cut in half is the diameter of the "pitch circle". Instead, the bases and tips of the teeth need to be the same distance away from each other in both sizes of gear. Your teeth do not have the same depth as each other because you are simply cutting all your dimensions in half. I won't bother going into the details of a properly engineered gear, but just how to get yours to "look right".
