Author's Note: Classic detailed illustrative logos are my favourites. Man! I enjoyed doing this...
This is an accomplishment after hours and hours of eagle profile study, some sketches and a dedicated vector illustration which is quite detailed yet recognisable at less than 200px wide.
I have also shown the original sketch as an additional attachment, zoom to have a closer look at the details.
I can further tweak it suit clients requirements.
I couldnt finish up the simpler version(6 color) on time...:(
