It's a nice model, but like the rest of his it doesn't fit in at all.
Who are you to decide what will and will not fit in. You have no clue what it will look like with a blockhead holding it, and nor do I as of now. I model in this "style" to make the first-person viewing as epic as possible, not so that everything looks like it was made out of a bunch of cardboard boxes glued together and painted.
And if it doesn't "Fit in", then I don't really give a forget. It's called DIVERSITY people. Do you have any idea how loving BORING blockland would be if every single weapon conformed to a definite style? My god. I am sick of having to remake this point every 2 minutes. Whoever thought of the "Blockland HAS to be entirely blocko" idea needs to be shot, along with all of his or her followers.
