Responsive design: Stats card using flexbox

I found the color overlay on the picture a bit difficult to get correct. I don't know if the background with a linear gradient is the way to go. I'm a bit unsure of the positioning of the image on the mobile part. On the desktop part of it, the image aligned naturally to the right, because of its position in the HTML file. Is there a way to get the image to show on top without making its position absolute?
