Ok so I'm trying to copy these cookies I found here on CC. I am making the Wiggles Big Red Car cake for my son's bday, but for Children's Day Out they don't allow cupcakes or cakes so I was in shock when I saw these cookies anyways I used a Wilton cookie cutter for a car and cut the top off but I messed up at the wheels the circle in the middle doesn't leave enough room for the multicolored rims like the Wiggles Car!!!!!!!!!!! Is my cookie may be too small the girl that originally made these have those colors on the rim and mine aren't big enough anyways I make no sense just see for yourself once again always thanks for your help!!! oops no attachment here it is

what about making the black circle in the center just a small black dot?? and also maybe outline the wheels in the black first utilizing more of the shape of the tires....and then fill in the red once the wheels are done. To me it looks like you still have some room on the wheels around the edges......try to line the black right on the very edge of the wheels and up higher onto the car too....that should give you more room for the colors on the wheels
