Boyd,
So far so good...
A mild critique...The best kind I think...
Shot 0 is your image as uploaded. I have placed hue clocks on the frame to show what is going on. Something you will be learning more about in CM101. If you look at the hue clocks that show the skin tones you see that they are all in an acceptable place...the hand is pointing between 1 and 1:30 on the clock. This is generally a good zone for skin tones...but; The hue clock on the sweatshirt tells a different tale. It shows a cyan/green cast...
Shot 1 shows your image with a neutral point place on the sweatshirt. Right click on the sweatshirt area and choose "set neutral" you will see as shown that the shirt becomes neutral and the skin tones warm up a bit...
Great job overall...this is exactly the stuff we are going to cover in the class.
