Creating an isometric map step by step

This is a step by step tutorial to create an isometric projection map of an underground dungeon location.

This is the finished illustration.

I always start with a crude sketch

Then I add the main linework and features.

I added a dropdown portray of the ground. The other options i to draw the walls but that sometimes makes the drawing to blotted.

Now I added doors

Now I add furniture here

I added rocky details to the drop down floors to give it depth.

Now I do the same with all the floor and walls in the bottom room to give it texture and depth.

I added a margin and a secret room and a deadly trap in the second chamber.

Final details like number tags and a shaded layer to give some sense of light.

Thanks for reading this far ! it's a pleasure to share my work process and pictures/drawings.

Have an awesome day.
