That is simply awesome work, I love the step by steps. There is a ton of detail in that picture, even down to the bright spot on the floor from the window, and even the small shelves under the ladder. Those are the kind of things that make a drawing come to life.
Have a bless day
It's great to see that the hard work for these details was not for nothing :D
lol, but it's not really about this drawing, it's more about the book. Do you write with the same level of detail?
