I am looking at this and maybe it is my WWII Operation Whitebox still hanging around, but I can imagine a bunch of POWs trying to build a glider in the attic!
This is another practice image. What I learned is that lettering is harder that it looks!
#Inktober allegedly advanced cubes
The problem with letters is that you aren’t writing letters, due to perspective. So, to get the letters to look right, they need to be drawn wrong. It can help to use top and bottom guidelines tapering off to the vanishing point, so that the tops and bottoms of the letters taper off correctly.
I did draw the guidelines in, then rubbed them out from the final image. I am just not very good at this. I do think I am improving, or at least still finding my level.
I have seen your images on Instagram https://www.instagram.com/azkukailgames/ I think you are a level above me in talent, but then you have stock art for sale on DriveThruRPG as well. https://www.drivethrurpg.com/browse/pub/6582/Azukail-Games/subcategory/20430_24571/Stock-Art
I was once pretty decent at sketching – won the art prize twice in junior school. So, a long time ago. However, I couldn’t paint with those big watercolour blocks at all.
