No, it isn't bad at all....just doesn't look as good as it should. As in it would look miles better if there was motion going on.
Did you use the default shutter speed for the pic?
Just to give you an idea. For most of my racing shots, I normally use Panning Mode 3, lower the Shutter Speed as far down as it can go, I think it's around 60 (?) and Focus at 4.0, then aim at the car, and press square for auto-focus.
I feel like if you'd done that, that shot of the RX-7 would have looked great.
But hey, I'm still learning too, I'm sure there's lot's of other theories.
Just keep practising, you can already see improvement through your gallery 👍
