And it was originally from Angels and Demons. This is nearly identical to the picture you linked to, as in only a couple of pixels are different. So, I'm sending this back as Pixeljoint only accepts stuff you yourself have done.
Please don't feel disheartened though, I wanna see more works from you in the future. Also don't be afraid to take your in-progress works to the WIP forum :)
not quite, I used this database: http://www.deviantart.com/download/104737842/Illuminati_Diamond_by_alcnaurewen.jpg
Thank you for your comment
PS: If you find that I write bad English, this was the fault of google translate^^
