I have an image I am working on, and the original idea had a child holding a sword, which I made very obvious was a wooden toy sword. However, I wanted to change it to a toy gun, which would be designed more towards a spacey themed laser gun, much like Marvin the Martian's gun, or something from toy story's use of scifi laser style guns. Is this going to be an issue for my portfolio?
I wouldn't think so? Buzz Lightyear carries and shoots a sci-fi gun without any issues, like you mention. It's probably fine as long as it doesn't resemble a real ak-47 or some such c:
