Help with perspective

[Cloderick]

Hello guys.
Here I'm asking for help.
This time i started working in a background and i get stuck
with the perspective,i need to put a circle on these platforms
i tried for an hour and i gived up.So before i move on in another
perspective i wanted to see if someone can help me,maybe its easy and
i just dont figured out how to do this.
So,i need the circles to fit these columns and do a circle platform below them.

Welcome!

So what you're trying to do here is one-point perspective. Making sure all points go to ONE Vanishing point.
With that said, this picture isn't in perspective because there are a lot of parallel lines. You might want to start with establishing the horizon line, your vanishing point(s) and then plotting lines to them for accurate perspective. 

As for the cylindrical pillars, they're quite easy. We'll get to it next, but let's first make sure you understand this first. 

(Hint : You can construct them very easily using cuboids and ellipses!)
