the first one was on a tutorial witch i found to be boring so i improved it. The second one i wanted to create a spaceship and i made one....I know the official way to model is to draw it first on paper in diff aspects and the load em up n make em 3d....sound boring don't it?
I sometimes sketch on paper what I want it to look like, but I never draw them in the aspects and 'trace' them in 3D. Too timeconsuming and unflexible.
