It is a fine line for sure. Your character has hints of looking like some character from movies.
If you are not selling it or not using it in a commercial game, all should be fine.
In a commercial game you (graphix), may need to sign a release form for use to whom ever wants to use it in the commercial game.
As far as weapons go, there was a discussion around 3 years ago which would have put most of the stock weapons in question, just because of what they are named. But no further info came from that and Game Guru as far as I know, have not received a C&D letter for them.
Fine line.
For all that are gathering media for commercial games, It is best to get a signed release from the artist you get your media from.
Will make your life a bit easier when it comes time to publish, or you use a publishing company.
Thanks for the Character.
