No reason to think it isn't. Post dates of images are same on DA & OP. Artwork posted by OP elsewhere roughly matches the style (and is of similar quality) of images OP posted in this thread, which incidentally are not on the DA account but which also match the style of artwork on the DA account holder's employer (or company), EverdreamSoft which has developed Moonga (which you see reference to in the DA account) and is developing a new offering called Spells of Orbital (a name I'd assume was come up with on LSD). I can't say for sure who the OP is, by legal name, but am certain the OP is at least associated with the company holding copyright on the images, and would assume the OP is likely Shaban Shaame, but possibly Elodie Bastide. This doesn't necessarily mean OP created the images, but that it's likely he holds copyright on it.
This is correct ! But would you mind remove my email from the topic
you can rather use info at everdreamsoft I get these mails as well !
