It's a nice image! The blue color is very eye-catching, but perhaps a bit too-blue for the subject? I would be interested to see your "pale" blue version (before editing), because I have found the blue morning glory to be a very challenging subject, color-wise.
I have been photographing blue morning glories for decades using a variety of film (mostly transparencies) and 2 different digital cameras, and the photographs almost always turn out significantly more violet than what I saw. So far, my best result for color accuracy was from a Fuji XE2 using Fuji's Astia color profile, early one morning before sunup. But if I take that same raw image and switch to another color profile in Lightroom, like Adobe Color, the blue shifts to violet. (If you want to see my blue morning glory on my SmugMug site <

I just realized I haven't tried this subject with my Pentax K-3 - and I think I saw some morning glories in the garden today - so I will try that tomorrow!
