To make the castle look super realistic and three-dimensional, add some shadows under the roofs and balconies, as well as along the towers' sides. Don't forget to colour in the flags!

Since you added shadows in the last step, it's now time to include some highlights, so that it looks like the sun is shining on your castle. Also, finish adding the Brightvale colours to the flags. There you have it - your very own drawing of King Hagan's beautiful castle!
