Good scans... liquid mounting what??

I finally have some good scans for you. I've already posted these images but I like them a lot. Today I tried the liquid mounting for the Epson V750pro scanner and it works really well although its a bit bizarre. You pour a special liquid substance on a glass plate and then just stick your raw negative on it and then pour more liquid on top of it and cap it with a piece of mylar. It's weird and a bit scary but it works!!

PS- the top scan was done with a tray, and the bottom one with liquid mounting. Can you tell the difference in sharpness and grain??
