Transparency and shadow problems while exporting
Hi everyone,
I'm working on a website for a client and I'm experimenting with transparency and shadow effects for the first time. We've incorporated these "paper cut" effects throughout the website, but the effect isn't the same when I export as a PNG. The below screenshot is essentially what the effect should look like on a solid color background or white/transparent.

Now the idea is to have these "paper cuts" attached to a photo that floats over the parallax background on the website. Something like below. In this particular example, the two paper cut shadows would be grouped with the photo of the puppy and exported as one PNG.

Here is a shot of my export settings:

And here is the result:


I'm hoping that it's a simple fix and I just need to adjust colors or something. I've exhausted my resources and I need some help from you guys.
Thanks in advance! I'd be happy to offer up any more information if needed.
