Logo image too small

Good day,
I am using the Botiga theme for an online ecommerce shop. I am struggling with the logo. I have used several size images and the suggested size, but it still stays extremely small, almost unreadable. the site is: www.scatteredfashion.co.za
Please advise on how I can get the logo bigger. I tried the header image way, but then it places the header image below the menu. Am I doing something wrong?

Hi,

First of all, thank you for using our Botiga theme. I am happy to help with your queries.

I checked your website’s and it is readable on desktop screen. Are you referring to the small logo on mobile screen and wanting to enlarge it? Please confirm.

Regards,
