Logo is not displayed correctly

hello, i am using the free version of astrid. I have a problem with my logo:
when i insert it, the image looks compressed and not sharp. can you tell me where the problem is?

I have inserted the following into the css:

    .site-header {
      padding-top: 10px;
      padding-bottom: 4px;
    }
    .custom-logo-link img {
    height: auto!important;
    max-height: none!important;
    }

here the link:

Hello there,

I am sorry I couldn’t notice the issue as it looks good compared to the original image file uploaded.

Probably you should redesign your logo and maintain its sharpness.
