That looks great, good job! I do cerakoting in my gunsmith shop and you may already know but it requires application with a hvlp spray gun and heat curing in a special oven at 250 degrees F for one hour for metal parts and up to 150 degrees F for plastic parts and is single colors. Surface prep for Cerakote is labor intensive and detail critical. There is another method called Duracoating that I also do in my shop that is sprayed on with an air brush usually, you can use templates to create any camo pattern and has a lot bigger color selection palate. It is an air cure two part spray epoxy, its not as durable as cerakoting but still holds up very well against scratches, etc. Hydrographic film would definitely be the way to go I think. You can buy the kits and do it yourself without any special tools. Lots of firearm manufacturers are using hydrographic film to camo their guns at the factory.
Again good job on the detail!
