That looks simply amazing!!!
I don't mean to critique your F-18, but it looks to me as though you've carved it using a fairly large feather setting. Have you considered carving a circle around it, to the depth, so that it will give the F-18 a bit more 'pop'? I noticed that your cut lines do form a bit of a circle, so it would probably take very little work to have it carved in the centre of the existing circle on the back.
My two cents - I certainly don't mean to offend. This is amazing, beautiful work!
