Hi there. I'm sorry about the late response. If it has been been taken by camera but in a reasonable way where it's not photography, then I would post in whichever art style your work applies to - traditional, digital etc. This group doesn't accept work in progress pictures I'm afraid, just completed art.
If you will be posting regularly for your miniatures project and these are to do with Game of Thrones/A Song of Ice and Fire in any way, I can consider making you a folder for that.
Hope I have been of some help to you.
Nym.
