Hi Rabbit,
The logo looks great. There is good detail in the image. Shame about the film leaving a mark.
Some thoughts (probably silly)
Was the film the temporary vinyl? Would a few coats of clear cover the marks?
Did you try making a cricut stencil of your Dragon Logo?
What about using permanent silver (Shimmer!) vinyl to make your logo - and then try to bury that under a few clear coats?
