I got some free time these last nights to finish off with this personal project. As there was no model-sheets and few good references, I do have to say that I learned a lot with it and pass through a bunch of problem / solving situations.
First idea I wanted to have just one render of the model, but during the process evolution, I ended up working in the topology, making it all four sided polygons and reduction the polygons count.
