where do I go from here? please help

Hi, I just started blender and my only help is the essential blender book. I think I know about the basics, like extrude and loop cuts.

I want to make better models, specifically low poly (2000 ish?) game models. But I feel stucked right now because I don’t know where to go next. Most tutorials are too difficult or confusing for my level.

This is what I can do with my current level:

Thanks for your time.
