This is an illustration from Giddy The Great showing Giddy Goat climbing the Eiffel Tower:
Since I live in Sheffield and not Paris, I downloaded a photograph of the Eiffel Tower from the internet, using Google Images (a wondrous reference tool for illustrators – I remember the days when I had to travel to the library and trawl through books). The Eiffel Tower is a tricky shape.
This was my first sketch:
Not bad, but a bit boring. So I made the tower smaller, to open up more foreground, where I could introduce the little Parisian animals sitting on the rooftops, watching Giddy climb. I gave the mouse binoculars, the bird a beret: I was having much more fun. Then I moved Giddy a little higher up the tower, to balance the composition. Much better all round!
