Adding details to model kit ejection seats

I just started building a 1:72 scale F/A-18F Hornet from Hasegawa. The kit's detail overall is pretty nice, but the cockpit is very plain. This isn't a big deal to me since I want to build this kit with the canopy closed. Still, the orignal seats are a bit too simple. 

What I did was really minor yet I believe adds interest. After an hour of effort, I made harnesses from Tamiya tape and sliced up a few stryene bits to suggest mechanical shapes missing from the original part. I just used scrap styrene and stretched sprue heated over a candle. 

I painted the seats in the same style I would use for game miniatures; high contrast and edge highlights. No need for washes or drybrushing. Simple painting techniques are yet another way to add details.

It's been a long time since I last painted and weathered vinyl tank tracks. Here are the in progress pictures from my current model, an old Tamiya 1/35 1A2 Marder.

They're ok. Not sure the final drybrush of Stone Grey was necessary but they just looked so monochromatic before that application. I think I'll add more pigments once the tracks are mounted to the chassis. Next time I may try Vallejo's Panzer Ace Track Primer instead of the combo of Tamiya's Flat Aluminum + Flat Earth. I avoided using Vallejo since I wasn't sure it could stand up to the abuse of weathering.
