I studied today and the results are in this photo.

Some nice cleaning work here, but what you need to be careful of is that it's a very noisy base image, so when you use the smudge tool you lose some of that noise, so you can see where it's been 'cleaned'. Try and use the clone stamp or copy and paste another bit of the paint over the area in cases like this

You may also wish to try using bases in which you can see a little more of the side of the car - it gives you more options for modification and often produces a slightly more interesting chop
Keep going - I hope to see some more work from you over the next couple of weeks
