It's a start but there's still plenty of room to create a more professional looking image.
1. I don't feel like there is any true focal point, my eye doesn't get drawn to a specific part of the image. Your job as the photographer is to guide me through the image. Do you want me to look at the badge, the bulge in the bonnet, the carbon detailing or something else? You can do this with selective focus, framing or even lighting.
2. I think with this image you were probably trying to emphasise or at least show off the contours on the bonnet, if that's what you were trying to do then I think you've got the general idea. Perhaps you could try a few different angles and possibly try to draw some hard, contrasty light across the bonnet; that'll really show off that crazy bulge!
3. With this kind of 'stock' car photo the background is as important as the car. Your background is quite distracting, there's people, cars, signs and heavily contrasting light. I understand that you might not be able to control these things but I've had that problem too! What I'm always told is that everything in the image has to have a purpose, this applies most importantly to photography like this. You've framed it well and I can see where I'm meant to be looking, I'm just being pulled elsewhere.
I attached a shot of mine, purely for illustration, I'm not saying it's good but it might help you. There's nothing in the background that I don't want, it's not too distracting there's no people, signs or other cars. That's partly thanks to photoshop because there was a huge building and loads of signs, but there's always somewhere without people!
I think it's a nice car and it's got potential!
