Again, these look REALLY excellent!
The Blood Money one reminds me of Menacing (the left side of it at least). Agony is awesome; what is that sack-looking thing on the upper left? (note that I've never played these Psygnosis games before) I had to convert these to NeoLemmix because it's hard for me these days to view them in traditional Lemmix.
Sorry I didn't reply to you right away about the BeastIII. I really enjoyed that level and the 99 release rate made it tricky, and it really feels like it would fit in Orig Lemmings (along with the other VGASPECS). I have a replay but I'll post it when I get to my home computer. I'm probably also going to build an NXP with these VGASPEC levels (including your BeastIII level) in case people want to see what they look like.
