In making this I learnt how to use more than one screen to accurately measure the shape of objects to match a reference image.
I learnt how to use modifiers to affect an object's shape and duplicate them to quickly create more of the exact shape.
To create this I had to use extrusions and loop cuts to create detail and curved edges.
I didn't find this difficult but it took a long time because I was still learning how to use Blender and there was a lot of new things to learn from the video.
