Technical issues Rejections

I agree with Ralph that soft focus is the technical issue for which these were rejected; however, you should be able to sharpen them enough to pass. I find that Photoshop Smart Sharpen does a good job in these instances. Always zoom in to at least 100% to inspect your images before submiting to Adobe Stock. Had you done so on these images, the fact that the eyes are not in sharp focus would have been obvious.

Beautiful photos. I think the main rejection reason is thge soft focus. I feel the photo's point of interest should be a little sharper. Probably your lens is too wide open because you want the background blurred. Concentrate more on depth of field.
