Release form for artwork ?

/
/I did a search and couldn't find an answer to this - sorry if I didn't look properly. 


I used to make plasticine models as a hobby and recently thought of the idea of making "people" doing different things for a concept I have in mind . It won't be simple images of artistic models , it will be concepts that would be difficult to get actual people doing. So my question is whether I need to have some sort of model release form filled out specifying that the artwork is my own - to prevent images being rejected for 'copyright' reasons perhaps .


Here's a "very rough" sample of the concept which I am working on improving but just to give an idea of what I'm talking about . I know it needs a lot of work [ would the globe of the earth perhaps cause copyright issues as well ? It's a $2 piece of junk ]

Yes, I would fill out a release form giving yourself permission to use your own work.  I have had to do that with my drawings. 


 


You can make the globe your own, too, by painting over it, covering up the text, and making the colors more true to life.   Then you'll have a prop you can use for lots of thins.

Thanks very much - very useful answer and much appreciated
