Here is the completed force from Jake's Get Started Tyranid box.
I saw some of these in person last night and I especially like how Jake has used some spare bio-morphs to make bugs on the bases as well.
You can see more in depth photos and descriptions on Jake's blog "Boyo Paints" in the sidebar. Here is a direct link to his Hive Tyrant article.
Now that Jake and I have finished our first 400 points and a couple other participants are not too far behind, its time to think about what step 2 will be.
