I dont think its easy to capture the sparkles.. look at guntars car, it has like a ton more prizmatique than u and it barely shows up in any pic.
The best bet is REAL bright sunlight.
Plus i think ontop of the marsmellow pink its more suttle and doesnt jump out and sceam OH MY GOD SPARKLES at everyone. Hehe
The ones that did come out of guntars looked a little rough.. looked like a shit paitjob rather than a nice sparkle.
No sparkles..
Not to bad.. but never looks great in pics anyway..
And then you get..
OH MY GOD SOMEONE PLEASE LOOK AT ME! lol
It will just never look as nice in a photo.
