Hey @dmcjason,
Glad you have decided to find the motivation to try modeling again.
As for your muscle car,
Well the lighting isn’t great, but the REV course doesn’t teach you anything about lighting, so don’t worry about that just yet.
For the low poly muscle car, it looks very good. You have managed to model a decent muscle car whilst maintaining the low poly style.
Well done!
Keep it going and practice, practice, practice.
