Anybody Know About Perspective?

Anybody know anything about perspective? I started learning Blender to be able to do art and do art references. That is why realistic models are my thing. At any rate, I noticed that the perspective is not the same as when you are drawing single point perspective.

I was watching an art teacher on youtube and he drew some lightsabers I tried to do that in Blender and did not get the same distorted result he got.

So, anybody, can you explain how perspective works in Blender and am I getting realistic perspective?

Hey Cats! For the perspective you can try going into camera view 0 on the numpad and then go to the camera settings. there you can change the perspective to orthographic or others and also by changing the focal length you can change the perspective
