Redoing some world art

So my game scored 21st overall out of 72 games made for the JamesPlusJam 2021.  Fun scored the highest at 18th overall, but my art was the lowest.  This is understandable, as I've never seen myself as much of an artsy person.  I have decided to redo some of the art for my game, so that I can get some practice in this subject.

I've decided to redo my buildings first, which were just isometric cubes in the Jam version.  So I started with just a bit of line work for the first building.  I then tried out 6 different pallets to color the buildings.  Next I am busy adding props to each of the buildings, so that I essentially get 6 game assets from the 1 building created.  So far I've done a hospital and an arcade.  I'm working a bit slower since the Jam is over, but have set myself a week to complete the 6 buildings.  So far so good.

The art is still faaarrrr from perfect, but I do think it is an improvement over the Jam versions cubes.  Once I have the 6 pieces done, I will implement them into the game with colliders.  I want to first see how Unity 2D lighting looks on them, before I waste time on shading them in my art software (Sketchbook).
