And here are a few pictures of all eight of them from this first batch. I'll do another eight to add to them to make a squad of 16 upgraded Hormagaunts.
I'm sure fellow Tyranid players have noticed that these Hormagaunt miniatures don't balance very well. the combination of their poses leaning so far forward and them being light makes them tip over very easily. I was sick of my Hormagaunts falling all over each other all the time, and came up with a solution. I took some small lead weights (in this case scavenged from curtain weights), flattened them out a bit so they'd fit in the Hormagaunt bases, and cut them into squares. Then I glued one under the base of each Hormagaunt, near the back. You can see the results in the picture below.
That little piece of lead is all that's really needed to make these models much more stable. If you used bigger pieces you could probably make them impossible to tip over. If you don't have any curtain weights laying around, you could always buy any other kind of lead weight. Lead is very soft, so it is easy to flatten out and cut to the size you need. Here are some lead weights I found on amazon.com that should work really well.
