Updates:
The first version had some high-compressed pixellation artefacts caused by excessive adjustment layers that weren't visible to me on my old setup, but on recent viewing with higher graphical setttings looked terrible!
So I've manually redrawn the vectors piecemeal on the UV in vector instead of projecting/baking in 3D and then shifting the colours at a later point.

I've also made some very tiny visual tweaks such as adding paint drips, splats, and minor texture detail.

Fixed a few minor misaligned seams - such as on the handle, underneath the stock, and the lower front portion; also redrew the belly artwork on the handle for smoothness. Some very minor alpha tweaks that improve the FN state.
