If you want to learn how to create models from scratch, your at the completely wrong place.
While many members here will give helpful advice, we have no tutorials etc... that a modeling dedicated forum would. Do a search for 3dsMax, Milkshape, or skethup for that matter and start there. It's not a simple as jumping up one day and deciding you want to model.
You also have to find someone to texture it once it's created(or do it yourself). this stuff doesn't happen overnight, and the APZ cloud model took quite a bit of time to create, and it shows. It's the best replacement cloud available now(and probably ever).
Read all the tutorials you can find! that's the best bit of advice i can give you.
