I can draw dinosaurs, animals and stuff of that nature pretty well but I absolutely suck when it comes to drawing transformers. I really want to learn to draw Transformers and come up with my own original design but when drawing, I don't know what kind of details to add to make it unique. Plus I have trouble drawing humanoid faces. I saw one guide on drawing anime/manga-style mecha in Newbury Comics once but I can't remember the exact name of it. I own one guide (Lets Draw Manga: Transforming Robots. Interesting how they never actually mention the "Transformers" brand ONCE in the entire book.) If you guys can give me some recommendations that would help. Drawing mecha (Any style) or just sci-fi stuff in general would be most helpful. I'd imagine too that books on drawing vehicles would also come in handy when designing Transformers, as I also suck at that too.
