Exercise 3: Colour Study I used acrylic and marker for it.
Exercise 4 Prompt Study. I used pencils for this one.
Exercise 5: I did not finish my sketch in 30 minutes so I will show you what I did in 30 minutes and the finished piece which all together took me an hour. I'm just slow as I tend to be shaky if I am faster.
