Nice work Vic. I remember a build review when this kit was released, and there were fit problems then too. And yes, it shares common parts with a Seafire kit, hence the panel cover the opening for the arrestor hook panel.
Difficult choice on the colour scheme, especially as the tonal reproduction in the second pic is quite dark. Looking at the underside in the second pic, it's obviously no Sky or MSG, so I'm assuming that's Azure, looking very dark. If thta's the case, then I'd suggest that the top colours are Stone and Dark Earth.
