Having completed the Omega SE1 about one month ago, I have decided to continue on drawing the Omega UT1, the first SUV of the series.
I plan the Omega line-up to look like something like this:
SE for Sedan (a 4-door car)
SP for Sport (a "nicer", slightly larger version of the SE)
CP for Coupe (a 2-door car)
UT for Utility (a compact SUV)
LT for Large (a full-size SUV)
W for Special (the special-edition vehicle)
(I do not yet know if the Omega brand will carry the VN for Minivan and TR for Truck. Probably not.)
Sadly, I have given up on three-dimensionalizing the car because I haven't drawn the original car to take into account extrusions (which is still probably the wrong way of making the car 3-D). I will stick with Front-Side-Rear views for now.
