Decent tut...
This is a pretty good tutorial for beginners. This tutorial can help with some of the basics of shapes and shading as well as what to start with and what the finishing touches are. Fairly well detailed in how the process works. However, it won't necessarily help in some areas, like drawing people and natural scenery (forests, prairies, etc). Also, it doesn't cover other necessary basics, like how using a trapezoid as opposed to a square creates more depth. Aside from that, it can really help new artists that feel overwhelmed by the process needed to make something look good.
Also, the mech and docking bay (I assume it is a docking bay) look good. Showing such good designs can also help new artists understand the tutorial.
