Better circle - Right or wrong?

Can we say “Draw a better circle”, when all we want to say is to draw a better approximation of a circle, than the one which the person, we are speaking to, has already drawn?
What about usages like more perfect, more complete etc?
Do these words have their comparative forms?

Hi,

Usually when the adjective suggests that there is no possible improvement, there is no comparative form. Adjectives like ‘perfect’ ‘complete’ ‘unique’ and so on are examples of this.

Thx, Alan.
Coming back to my original question, the titular one, I guess we can’t use “a better circle” too. Is that right?

Hi,

That would be possible if you were referring to ‘a better drawn circle.’

Alan

I see. Thanks a lot.

Without the aid of a compass.
An attempted circle, which is not really good enough to be called one.
Now, draw a better circle.
