I like the concept in #40 and was just writing some suggestions when I stepped out the office, came back and you already implemented them on your own in #71. So lets look at #71 instead -
I wouldn't mess with the "depot" part any further its good, but I'd make the reflective "eliquid" less intense somehow either through color or typeface
I see what you're doing with the bottle, but I'd make it a little less subtle and lost the bottle, maybe liquid in the letter if you want to tie in the liquid theme.. overall i do like the concept here
