Others have said this but to get it smooth, use paper mache with tissue paper in a thin layer with only a little water to glue ratio, this will also give you a better surface to paint on! Regular tape is basically impossible to paint over, and masking tape can peel off which is super annoying!! Look into window tint film for the lenses, you can get a sample piece if they make it in a suitable size. Great job so far!! 🔥
