So here is my initial sketch for what I have envisaged.

Sooo, my rambling thoughts regarding building a wreck/ruin, I think that to make something look good as a wreck you have to build it fully but with all the 'bones' in so that the layers can be peeled back. That being said, this approach is so much harder than just building a shape so I've set myself a silly amount of work.

Here is the initial cut, as it were creating the first few pieces and ribs for my speeder.

Next step is to start roughing out the ribs and some panels and working out the base.
