i am really flattered that you want to add this photo to your FB cover, i am sorry that i cannot give you the permission you seek. XXX company now owns this photo, in another words, i can post this photo (since i took the photo, but i am not the legal owner any longer)
certainly, i wouldn't mind at all, but please understand i can only give my most honest feedback without being disrespectful and malicious. some tips in advance, bring your finished baked goods to a window, borrowing indirect ambient light (best lighting available), remove cluster from your shot. if you do not have a tablecloth to enhance your cake, when in doubt, always use white as a default setting. i am not sure if you are familiar with WB (white balance), if not, Google the information then proceed.
WB issue is horribly rancid here on dA, only a handful of folks master this skill (from my detailed observations), even the most popular individual who posts her little cute animal all the time, her WB is off, in turn, offered a horrible photo result.
Lovely tea cups as always, any floral print is my Favorite, especially anything with roses. And chocolate dip cookies -^^- Yum <3 That cup closer to the watchers looks like the cinnamon tea my mom makes when we're sick or when its cold. Its lighter color reminds me of it Lovely -^^-
