Mecha Talk

I'm actually a pretty good artist in terms of raw talent, meaning: I've always possessed the skills necessary to make quality art, but have always been too lazy to improve my craft and refine my techniques. However, I have an outstanding idea in mind for a self-made graphic novel and I'd like to start working on it in the fall of this year after I flesh out the elements a bit more and continuously practice at drawing. So, would any of you know of some great tutorials I could use on a daily basis, starting with character drawing, as well as mecha and city/landscapes? I'd appreciate it greatly.
