Good job, that is definitively a good start. I started myself recently (one year), so take my critiques lightly

#2 really like, sharp with a great bokeh!
#7 looks like straight out of a car magazine, awesome job!
#9 the sky is blown out. Are you using a flash? If yes, try to meter on the background and fill light the car with flash.
#10 It would have been nice if you could had a more diffused light (more contrast on the purple flower). You could have placed a piece of cloth to diffuse sunlight on the flower.
Like I said, I still a noob too, but hopefully a noob can help another noob:mrgreen:
