but to show you in more detail, what is meant:
1: creating spline according to reference pic
2: creating a nurb object from it. shape can still be modified, just by editing the spline
3: conversion to a solid model (polygon-model) changing shape is now much more complicated (you have to edit points, edges or polygons), but you can define selections or manipulate the surface as you want (i.e. to add detail)
3a: not pictured: made the wings this time by poly-by-polymodeling. you can also use splines. then you make it the same way as the rocked-body
4: greebling the surface for details
5: light-setup, etc. and rendering, tweaking materials
hope that helps
