I made the logo area larger as I wanted more room for a bigger logo and it is now not showing properly when viewing on a mobile.

If you look at the site www.duskmothfaerie.com on a mobile you will see that the logo is being squashed and not showing with the correct proportions.

Any help most appreciated. Thank you.

Can I please get some assistance with this? I would really like the logo to display correctly with the correct proportions, when looking at the site using a mobile device. Thank you.
