Environmental Storytelling - Perspective

Perspective is something i have never really been very good at. The drawing of extra lines as guides didn't make sense to me and i couldn't wrap my head around it all so i want to research it and make it my main focus for the environmental drawings.

The starting aspect of perspective is your vanishing point and your horizon line. The horizon line is what we might call our eye level. Depending on the eye level,  your composition will change as you could be looking down with a low eye level or a really high level could mean looking up. The vanishing point is a point on the horizon where all objects gravitate towards and vanish. There can be multiple vanishing points in one image with a maximum of three showing the three dimensions that exist height, length and depth. The multiple guide lines can be really confusing as well as distracting as they over lay the lines of the drawing which is something I'm going to have to get used to.

These are a few of my practice attempts at trying to understand one and two point perspective, for the most part i don't think it went very well as my perspective isn't very clear and its too fixed on the guide lines and symmetrical.
