Looks great! I've done a couple of dozen of these over the years and I actually have one in my "To be done soon" pile. A few bits of advice and opinion.
Whenever I do laser blast holes and singe marks, I try to picture in my head the angle and direction of the attacker when they fired the shots. This way I get a more realistic looking pattern. Kind of like with machine gun holes in a car door or something. Generally the singe marks will all be in either a straight line or in an arcing pattern if the firing ship was turning relative to the Viper's course. Also the actual holes seem a bit bright to my eye. I would make them a shade of black or very dark grey. They almost look white in some spots.
I think you used Model Master "Jet Exhaust" or something close to it for the engine outlets and the detail of the engine piping and cabling just behind the intakes. I would probably use something a bit more gray as a wash over it to bring out some more detail. In the show, they were a dark flint gray like color. With mine, I usually use that color as a base, then do individual detailing on the various components and then a wash to dirty it up a bit.
There is an eBay seller on here that I have found to be a great source for inexpensive lighting for the viper. He can custom make an LED lighting pack with 3 light blue and one white LED with resistors and set to run off of a single 9 volt battery. I got a set like that for like $15 or so. I use the 3 Blue ones for the engines, and the white one to illuminate the panels in the cockpit, and they look great. I also bought a smaller set of 2 white for one of my Raider kits. He does good work. I can't remember the seller name but if you search on eBay for LED Lights, in the toys category, you will probably see his items there. The Viper looks great when lit like that. You may need to take off the blue colored paint you used on the clear engine plastic, but it really would be worth it. I am planning on mounting a mono earphone jack in the viper and a plug in the base that I can power it up with on the stand. Using a power switch, unless I can find a switch small enough to put somewhere hidden on the Viper itself. Using the base for power takes away the problem of opeing up the body in some way to mount the battery in the ship.
Just some suggestions. It looks really nice as is though.
