Back To Square One

I decided I'm going to do some basic modeling and texturing as I've never really spent much time on learning the foundations of 3D graphics. So, here's a cardboard box. During the process, I realized I don't know as much as I thought I did.. I really need to be honest with myself and start from the beginning again. My box turned out to look like Team Fortress 2, which is not really what I was going for lol..
