Professional image editors and photographers, would use their included cloud storage more often for customer presentations or to collect feedback on their work if the preview images would actually be sharp. The only reason I'm currently forced to use other services like picdrop.com is because the preview images in Adobe CC's web-based asset viewer look very unsharp, especially on high-res displays. If you could manage to generate sharp image previews, professionals would be able to use the cloud storage to collect customer feedback without constantly receiving complains about the pictures being unsharp.

I've attached two examples, so you can take a closer look.
