Here are 2 more members of my planned 5 man Sternguard Veterans Squad. The veteran to the left is armed with the special bolter which fires 4 different types of ammunition that the unit gets as their default weapon. He's had some very minor conversions done to him; for instance, his right shoulder pad is from the Command Squad kit and his bolter is from the Black Templars kit with a standard storm bolter box magazine glued to its bottom. Again, paint-wise, he's fairly standard for me. I like how he looks suitably decorated - it definitely gives him a veteran feel without going overboard with the embellishments.
The veteran to the right wields the Heavy Bolter. I actually think he turned out really well. I love his pose (which was achieved by using a pair of legs from the new Blood Angels Death Company kit). He certainly has a sense of purposeful motion about him. His helmet is also from the Death Company kit. While not everything Blood Angels would fit well as Blood Ravens conversions, with some strategic scraping off of mismatched iconograpy and choosing of parts, there are enough in the new Blood Angels plastic kits to really allow a modestly-skilled modeler like me the ability to customize a standard Codex Astartes chapter like the Ravens.
