If you like to draw I think you'll like this. If you like to draw buildings, I think you'll love this! I sketch for fun and the tips and tutorials in this book help me make my sketches more complex without being stressful. 

I usually sketch the settings of whatever I'm reading, either from memory or from images online, and already I'm getting much better at perspective and colouring following the Albert Kiefer's advice. 

Even though I sketch on my iPad, if you prefer to use physical art supplies there is what seems very helpful information on which supplies to invest in and tips for using them, how to achieve the colours you are going for etc.
