I'm almost certain it is a Pastel Yellowbelly. In the baby picture, the black has flames in it. For two seasons in a row, I have bred my Orangebelly to a very high quality Pastel. Both seasons I have gotten a female Pastel and a female Pastel Orangebelly. After a couple of shed, there is little difference in their colors, but the Pastels have much bolder and solid blacks, the Pastel Orangebellies have great blushings on the back, on the neck and really awesome flames on the sides. Look at the baby picture again, you can see that the neck has some blushing on the sides and the flames are easy to see. Take a look at my Pastel Orangebelly, the second picture here (http://www.worldofballpythons.com/mo...-orange-belly/). You can see the blushings and flames in the pictures on World of Ball Pythons. As the animal in question has aged, it certainly has dulled down, which may be a sign of a lower quality line of Pastel being used. But I would still guess that it is indeed a Pastel Yellowbelly based on the baby picture.
