Stylized Gun in Blender - Timelapse

Model is based on concept of Max Davenport: (scroll down there) and it is a fan art. It is not a tutorial, but a timelapse of my workflow. Most of the gun is made with subdivision technique. There is a lot of modeling and fixing small details edge by edge, coming back, fixing again. Subdivision requires knowledge, good topology and some more tricky parts may need time (until get the idea what is the best). I do not know all the tricks, so it is as it is. I also would like to remind, there is a speed button on YouTube, because video may be boring (and it is quite long).
