image module smaller

this image on the bottom of module is smaller than any other module, do you know why? and can you fix it? thankyou

It due to the image ratio, with the current height, it will be cropped, I just added this custom css to force it displaying in full-width:

#acm-features-509 .features-image img {
    width: 100%;
}

Or another way is that you can edit the image so it fits the space of this section.

Regards
