Simieski- Thanks for the complement! I really appreciate it. So you know, these aren't finalized yet. Still tinkering with them. My plan is to completely remake the default icons while juggling a fulltime art director job & my 2nd shift-night time art director job.
As for BiteSMS and Spotify; they would have to pay to get new icons since they aren't apps I use or own LOL. Can't promise it, but I might make modifications of existing icons for for both BiteSMS and Spotify after I'm done with the set. Don't hold your breath
