Boat are often compare to birds, so why not see birds with sails ?
I've made several work in progress :[link][link][link]
All pictures used are from my personal collection.
Updates made : birds postion and some textures, tower lighting desing and texture and few other things...
I hope this one is better, for me it is
Second update : well the tower was still a hard point... i've made some try with a church photography but the very poor architecture of the building was not very good in the picture, even well integrated. So i've made the choice (not easy because i put a lot of time on the tower) to suppress any idea of building and continue with bird to give the gigantic scale, the result is far lighter and probably better, try to integrate a building was probably a bad idea in fact...
Thanx for all constructive critics
