Thanks for all the support I've been getting for my daily sketches. It's giving me a lot of incentive to keep trying and experimenting.
I didn't have time last night to colour in these 2-point perspective studies, so I did some quick photoshop work to suggest what I had in mind. I like how the galaxy turned out in the top one, which was made with a very simple technique I happened upon. The lower sketch is supposed to be a city covered with so many skyscrapers that only a small glimpse of the setting sun can be made out. A bit like Coruscant or Ilium.
