First, yes please do post a pic of your work, it will help target specific things.
Now here are mine:
what I did the same: yes the bike itself required layering. It's about 10 coats, and I did barely any shading. It can take more. The chevrons on the hood I did with scotch tape. Put down the top and one side of the bottom. Paint it with the hood color (one coat to make a seal in case the tape isn't perfect, then a couple coats of your color. Red on black IS REALLY HARD. Paint done white or pink in there first to help the red pop. Repeat with the other leg of the chevron. I let legs dry overnight too.
Different stuff:The back fins have some light shading on them. That's a subtle and wide hard edge highlight I believe. The arms are well shaded on his but not mine. I like watering down a color one shade darker, and hitting crevices. There is a good amount of shading in general on that model, that's what makes it look so nice.
This stuff all takes time. Painting with red, an hour is nothing.
