Let's start with Posh Spice! I actually ended up wearing this lipstick a lot before making this post so that's why it looks half empty on the pictures. The lipstick smells REALLY nice, like vanilla cake. But it's not that strong, so once you apply it to your lips it just fades away eventually. 
The first coat was slightly streaky and, out of the three, this one took much longer to dry and it didn't dry completely. After a few minutes it was still tacky and not 100% matte, but it's smudge-proof and it doesn't get flaky and cakey. It's also really long-lasting! In person, the fake looks nothing like the shade you see on Jeffree Star's website. The real Posh Spice has a nude color, more beige/light brown while the fake one has a hint of lavender.
Moving on to Doll Parts! This one smells like fruity bubblegum and it's soooo good I could eat it. The real Doll Parts looks lighter on the website, the fake one looks much brighter and more magenta. Unfortunately it's hard to tell the difference judging by pictures because even the real one looks different depending on the lighting, camera, filter, etc.
Last but not least, we have Unicorn Blood! This one smells like vanilla cake as well and it's really pleasant. A problem I have with lots of dark liquid lipsticks, not just fakes, is that most of them don't give you full coverage and it looks streaky even after two coats. This lipstick is not different.
Just like Doll Parts, it dried completely almost instantly, which is good... I think. The real one on the website looks like a deep dark brown, while the fake looks more like a purple-ish red. Again, I can't tell if that's accurate because lighting, filters, camera quality, monitor settings and all that stuff. This lipstick is also smudge-proof and long lasting.
