If your going to do 3d, your going to be sitting fore long periods of time. Take breaks, walk around, get some water. And get something for your body.

This page just has reviews of the new features in each version.   It's good to watch all of them just to have an idea of some of the things that Blender can do, and updates.

What is the difference between the following file formats - png  jpg and tiff by Peter

Ever see those concept art pictures of sci fi spaceships that were done in oil painting. (Syd Mead)  This persons technique is close to that style with a simple texture.  The thing that made me say wow that's awesome was that he uses a texture in color and alpha and a uv map to make those edge detail. 

Level of detail - and choosing texture size for images.

4k textures  of course is only for things close to the camera.

So level of detail or LOD is an important consideration and really the first stage when taking on any modeling job or designing models.

First thing you ask is will this be in foreground middle ground or back ground

Foreground of course is 4k,  middle and back 2k or even just hd would be enough.
