Overall a good job for the first attempt. You are on the right track, just need time to get it down pat.
What type of paints are you using?? If the gold is Createx Auto Air, the best way to spray it is to put the first coat on light. Build the second coat slowly until you get the desired effect. It also helps to play with your air settings and paint viscosity to prevent spitting.
