A rather interesting lesson in why you should always wear your helmet! However it suffers from out-of-focus photography, and poorly done metallics (especially on the bolter). The bolter barrel(s) should be drilled out too for maximum effect. I assume the glossy Tyranid is supposed to be "slimy" so I won't fault you for that, I actually do rather like it. I'd say fix that bolter and take a new photo, and this could be a 7!
