Fano, vieille branche, toi z'ici ?

Very very good. More, please.

Thx ! no need a reason to have fun ;)

Thx for advices, there was something that looks wrong but i was not able for found it.This is very new for me so i still have problems to mentaly represent volumes and to draw exactly as i want, lacking some techniques too.I quickly edited it and the result is quite good :D

Very nice.  I'm a fan of double-wide style so I like what you've done here.  About the only issue I see is some of the shading seems a bit off, like on that metal hook in front and the lower fin.  Otherwise I think it's great!

 sweet,  reminds me of Space Quest!  ^_^

Overall looks cool. Crits: I think that the form of the battleship is like zeppelin's, bubbly, so the sides should be round. But very large area of one colour makes it seem like it's side is flat (and panelling doesn't help). You can fix it by bringing shadow from bottom towards the center. Also you can accentuate metallic nature by lighing it from underside a bit (by using that colour from currently flat area).

Its probably cool to make things the hard way with a reason :)
