Yea i commented on that pic. If you still have the predraw prop it and the new one on a book or something and sit them side by side with a bright light on them for reference. That shit is WAY too dark tho yet the plunger looks intact (does it move freely or without feeling majorly stuck to the barrel?). Also when zoomed in on it there is a clear gradient with significant separation, first you have the clearer, yellow closest to the plunger then a drop to a darker yellow, then a bubble (so the darker is really light weight or really dense for that bubble not to move up) with a clear shift to green and then to almost black.
Try moving that plunger and with the darker portion to the top, see if the plunger moves first but also if that bubble does and see if the dark portion is so dense it doesn't want to flow. What gauge needle is that on it for reference?
Damn that stuff looks like ink on the top layer!
