the image won't load for me....
indeed, the parts on the main site are obsolete. I (and quite a lot other people) are working on renewing it.
I think the gun is still wrong, the picture I found showed an open mount. also, I think you can best draw your own crane with the pics, as this one looks faulty as well... although better then the old one.
you have quite a lot of shapes outlined in grey, if they stand out of the hull (as is the case here, IIRC) they need to be outlined in black.
anyway, it is getting better, keep up the good work, but watch out: it is still far from finished
