Maybe I'll make one when I have some free time. Here's a quick tutorial: In Photoshop I make a layer and fill it with a color. Then I use the Bevel & Emboss effect on it(in the Layer Style Options) and with the eraser tool I make the panels and holes on the hull of the ship. I make other layers on top and play around with Bevel & Emboss options to give it more detail. I use the Pencil tool and some times the Brush tool draw everything.
