I really like the engine, I hope mine look that good when I try to do a realistic paint job.
Also, could you do a quick walkthrough of how you're going to blend the fender flares to the body? I'm doing the same thing right now and am thinking of simply using white glue to fill the gap between the body and fenders, then letting that harden and sand it till it looks nice.
hench, on this particular build the sharp line where the flare meets the body is intentional. it will be cleanned up a little but wont be filled. but normally i use the tamyia putty or automotive glazing putty to blend in flares. just keep in mind when you do flares or a widebody to build as much as possible with styrene. this makes your bodywork little to none also gives you a better product and something that wont crack overtime
