The next letter I created was the letter A. To create it, I fused three box polygons using Booleans to create unions, and then to remove the excess parts that were unnecessary. I then created the beanie hat using half of a sphere which I then converted to an editable poly to give it more shape. I created the hair and beard using polygons with textures.
This is the end result:

I also created the structure of a microphone using an editable poly for the base.
I created the turntables using various polygons, and created the indentations on the speakers using the boolean tool. I then added a pair of headphones, and some textures to give the speakers and table a wooden feel, and a metallic look to the records and microphone.
