This is Seraphs old ref from 2018. Barry had some minor updates, adding three more tails, adding Pink to the color pallet and having pink with white diamond shaped pupils, while his hair turned from a silver-blue to darker blue color.
When i decided to add pink and diamond shaped pupils I had a big fondness for Pink Diamond from the cartoon "Steven Universe". Pink was a big inspiration to add to my fursona at the time. I remember watching Steven Universe as new episodes would come out maybe every few months. At the time nobody was really aware of who Rose Quartz was in the show besides a big hero and Stevens mom. The more i saw of Rose the more i liked her. But then the big episode came out where it was revealed that Rose was actually Pink Diamond. I remember that a lot of people actually hated her, and thought of her as a bad and horrible person(in this case, bad gem) for what she did and how she handled things. But i myself actually liked her a lot more, and kinda felt like i could sorta relate to her as-well.
I suppose that during this time period i myself felt like a horrible person. During this time period i had been in a dark place for a while, an old "bestfriend" had betrayed me and spread horrible rumors about some stuff... i was also thinking we were going to loose my father, he had been fighting cancer for about a year. My brother and i were kinda forced to pause starting collage and start working as soon as we graduated because of how much debt the house was accumulating since my father had been out of work for a while being in the hospital. I felt that for the first time in my life everything was crashing down, meanwhile my optimistic attitude and thinking was fading away more and more. I just felt useless and overwhelmed by everything i did.

Months later, little by little my father started to recover, and felt that things would start to get better. So i had made a decision to move out of state with the partner i had during that time. But even then...I felt that i was running away from my problems back at home. I felt like i was abandoning my family, to be happy elsewhere, and i felt horrible about my decisions at the time (still do). I felt that if i moved away i could finally start living my life, focus on myself, start to pursue collage and do what i wanted to do... at the end i didn’t do anything about it, instead i had to focus on getting a job and moving up from there to make enough for rent.

So thats what inspired the pink colors and diamond shaped pupils for Barry (Seraph now).
