I needed to rethink the way I put the structure on the canvas, because the last structure was pretty but it didn’t do what I intended! Which was to make the viewer feel as if they are looking up at a great space and height. I went back to the ink structures and started to rework things and make new sketches.

I went back to this ink sketch above after the last painting when realised this is much more like the shape I want to be creating in my paintings – adding a shape like this would make the viewer feel like they were underneath the structure looking up at it, into a great space.
I started to do a bunch of sketches in my sketchbook and what I realised was that my biggest struggles was how to position the lines of the shapes so that they looked three-dimensional. As soon as I thought of this it reminded me of the cuboid structures I used to do and I thought about adding a more structural shape into these cathedral shapes to help. This ink test that I drew into below shows this process of adding straight lines into the round structures:

After doing more sketches I had a bit of a lightbulb moment! I realised I had been mimicking the shapes of a cuboid in almost all the ink tests. So if I was struggling with the technicalities of this shape, I needed to start with an octagon shape which I could draw with accuracy, and then add the curvy cathedral shapes back on top once I got the perspective right. TAH DAH. I felt like I was going a lil bit full circle back to when I started to use the cuboid shapes in my painting last year. Especially with what I did next:
I didn’t have any wire so I masking taped some nails together into an octagon shape and used to see what angles lines would make when looking at the octagon shape from different positions underneath it. This is what I did with the cuboid shape last year and reusing the idea worked really well! I was able to make sketches from the cuboid shape that looked believable, and then the arches and details could be added later. WOOP.
