I really hate yellowjackets, but I think they look pretty cool. At the very least I want my tyranids to inspire fear in me, so I'm going to try and give them a yellow paint scheme with black markings like the bastards pictured above. I plan on shading the ridged areas with some kind of wash, maybe a darker yellow or light brown. I'm also going to use some kind of gloss at the end to shine them up a bit. Eugh, I get the skeevies just thinking about those little turds.
