Before trying to draw my sprites I looked at the origins of pixel art and how game sprites were built.
Due to restrictions with technology at this time game creators were limited with the detail they could put on their sprites. They had to create with pixels, which is basically a block of colour; which when composed together with other pixels can be used to create an image.
Tv's at this time had a low resolution which also impacted the amount of detail and colour that could be produced.

Technology also restricted the colour palettes in some of the first video games, as shown in the Mario sprite above. Mario consists of two colours, Brown and Red. Due to the low variety of colours to pick from the designers had to be smart with where they used certain colours, to avoid Mario's arms blending in with his body when he walked they placed red over-alls on him. This meant when Mario walks you can see the arm movement.
Having this much of a close look at the Mario sprite allowed me to see just how each pixel was used to make up the sprite, although it used very simple shapes, they are very distinctive and are very similar to how Mario is shown today and throughout the eras. An example of the simplicity in the way the pixels have been put together is in Mario's foot/shoe, which is made up of four pixels on the bottom row, and three pixels on the top row.
