I felt that I couldn’t move on to my final map until I got the pod drawing right. I looked for an image online to base my drawing on and selected this one:
Then I realised I didn’t visualise the columns properly either, so here they are, since they are a simple form I decided draw them from my memory. They are slim, tall and each of them is at different angle.
Only now I feel I can move on to drawing my final map.
