Mech Drawing Demo: Security Drone

https://davidheidhoff.gumroad.com/l/heid01

Includes a 120+ minute demo with commentary as well as a 20+ minute techniques video, original high resolution .psd and .jpg files, and my go-to drawing and painting brushes.
This video covers  drawing and painting techniques, some mechanical design theory (joints, hinges,...), Photoshop tips and more. It also touches on design principles, character design, and should give you a good overview of my general process.
