I chose perspective drawing as one of my short courses to follow. I've always found it interesting, but was too afraid to try it myself. 

For the course, I made my room in 1-point and 2-point perspective, after practicing them first.

First of all, I practiced putting cubic shapes into 1-point and then 2-point perspective.

I then tried 3-point perspective, which introduces more depth and is therefore more challenging.

After getting the hang of cubic shapes, I was taught how to make circular objects in perspective and practiced that in all perspectives.

I then began working on the ground plan of my room, dividing it into a sort of grid. This would later on simplify putting furniture into my room when drawing it in perspective.
I also drew 2 side views with a comparable grid.

Lastly, I made a somewhat quick sketch of my room in 1-point perspective before starting on my bigger, more detailed drawing.

While making this sketch I realized I had no idea how to draw a guitar in perspective, so I practiced it separately first.

And then this is my room in 1-point perspective, finished.

I then moved on to the 2-point perspective room. It started a bit rough, but I improved a lot and I'm pleased with the final result. 

I also documented the wireframe of my drawing.
