Best custom photo acoustic panels

My wife wants some family photos in the living room. I think the room needs some acoustic panels. Luckily I know that some companies offer custom panels with a photo you upload to them. Anybody have experience with this type of application and recommend a particular company over the others? Any bad experiences out there where the photo came out not looking like you’d hoped for? I have very little experience with acoustic treatments and honestly don’t know where to start. 
 

family room is open to kitchen. ~13x18 not including the kitchen (13x24ish). Living room portion has vaulted ceiling sloped only on one side with the peak at ~18ft…kitchen portion ceiling is 9ft. Two large doors/windows on one side of the long wall. Currently wife doesn’t want curtains on that wall. TV and speakers on the short wall far end from kitchen with built-in cabinets. Current speakers are B&W 685 s2’s, which are front-ported but also likely target for a future upgrade. Naim Uniti Star for amplification that unfortunately doesn’t offer room correction. So how much total area should I start with? I can put one between the two windows/doors and several on the wall across from that one. Thoughts, questions, and recommendations appreciated. Thanks in advance.
