Notes::
Most common grid sizes for isometric art are: 32x16 and 64x32.
*You just need to add depth and tweak it a little.
When you want to draw front view before turning it into isometric art, keep in mind that (when skewed to isometric view) the length of one line across an isometric tile equals the length of two sides of an isometric tile.
Draw the basic shape of the store.
Turn the Storefront from Isometric view to Front view.
Drag the left side up and the right side down.
Add depth and detail into the building.
Create a layer above the building layer, then draw with different color to avoid confusion. Change things little by little and erase any parts that should be hidden from view because of the change.
