Here's a flashable .zip file that you can place your bootanimation.zips inside of so people can flash it through TWRP. I use this for all the bootanimations I make. Just replace the bootanimation.zip that i have in /system/media/ with yours and then test it out. Hope this helps! https://drive.google.com/open?id=0B-...0E1TmZYRTZYX1E
Also, I think the bootanimation would look better without your logo at the bottom of it. Especially if you're trying to go for the simplistic and minimalist look.
