It looks good bro!

I think it looks really nice, engine came out pretty sweet. You're doing very well, you're well on your way to churning out some real nice builds!
Now, I'm hardly an expert, but you're asking for suggestions and advice, so here's my 2 cents:
You did a pretty good job on the paint, getiing it smooth and all, but next time shoot a couple coats of clear. Your paint will be deeper and shinier and you can polish it out to an amzaing finish. I'm still trying to get the hang of it, but I know there are many people who can whip out amazing finishes rather easily. It just takes practice.
Detail painting brings your model to a whole new level. Even if it is box stock, a model that has been well detail painted well can easily be a show winner. Get some more paints and a few very fine brushes, and practice on a few things. Then you can paint molded seat belts, dash board details, engine components, window rubbers, misc nuts and rivets and whatnot. Adding washes is also a great thing, it gives things like engine blocks and heads andpanel lines more realsim and depth.
Spend a few minutes (or hours

) going through AF's modeling tutorial bank, as well as places like briansmodelcars.com and scalewiki (both have large tutorial banks) and you'll learn tons. You'll probably hate me when you end up never being able to build a kit with out modifying it someway (I never finish builds

).
Good luck to you and good job on the Eclipse!
