Sketch: Doodles and Scribbles

My first model/render using the open source 3d program Blender. I never knew that Blender’s internal render could be this good. Now I’m confused. Which 3d program software should I use- 3ds Max, Maya or Blender? I know 3ds more than any 3d software, but I really wanted to master Maya ever since. On the other hand, Blender is the software that interests me the most right now. Oh Blender, I’m confused.
