This is a 10-15 min smudge practice using only the mouse. The point of this exercise is only to think about the colors, values and shapes.
Step 1: Take the first photo you find any photo
Step 2: Smudge it in order to find some interesting shapes and values. Use a stopwatch :D
Step 3: Move to the second photo
If you have any question do not hesitate to ask me!!!
Good luck!
