making 3d guitar in blender 3d

hello everyone, today I have made an acoustic guitar,
so have you ever hire someone to make some 3d model .sometime modeling take a lot of time but according to how long that one been in 3d modeling on work that can take 3hrs that one makes in 1hrs so I have made research for reason and I found that there are something that is not necessary to create it every day, that one which can be created one time and other time when you need it you can import it form you gallery thing like tablets,watches, you can import it and change something like texture on anything but without creating it from scratch again so that increase speed of you 3d modeling ,and I have started to make those materials so I will use it on my work that I will make, here I start by modeling guitar and next I will make an axe.
for some detail take look on screenshots

so thank you for you support to my works
