Once you clean up the wiring in the trunk and possibly relocate your amp, then your trunk will look good. I like the fact that you used black on your interior, it looks good, but as sixshooter said, it will wear off, especially on your armrest unless your missing an arm. The last car that I had, i painted a LOT of things on the interior and exterior, it looked good for a while(i painted the interior black, it was brown on a MX3) it wore off real quick on the areas that you are always touching... Something to keep in mind.
So I am a pic whore, you said it's ok to post pics so here ya go!
Since you have an SPI, I would def look into a rebuilt head, that doesnt have the valve seat issue before you go any further, then prolly source some Euro parts... Not a bad start, looks good
