Does an Extended License cover making a painting of a stock photo.

Hi All,

I would like to preface this question by saying that I have already read the License Terms & Agreements as well as the FAQs, so I'd really appreciate if you did not just refer me to those pages.  I've also read other forum posts asking similar questions, but would like a bit more clarity on how my specific intentions match up with the terms of an Extended License.  I would like to make a watercolor painting of a stock photo I found through Adobe Stock.  I paint in a realistic style, so my painting would be as close to the original photograph as my skills allow.  If I intend to make prints of my painting (wall prints, or on mugs/t-shirts etc.) to sell, would buying an Extended License of the reference photograph cover me legally?  I plan to give credit to the photographer on the prints' sale description as well.

Thanks so much!
