@Cries Again its just a preference thing. Some people like clean wolves, others don't care, some people strictly want talents, others just want rarity even if it supplies no real battle effects. Some people want Hero wolves, others don't care about vitals. Some people want battle wolves others just want a shiny trophy. Everyone is different
1. Must be a stock or free-to-use image. Shutterstock, dreamstime, unsplash, Pinterest, Google, other free "image sites", etc... are not considered stock due to prevalent art theft. A good source for stock images is Deviantart. [Click to read more about stock images.]
***An exception to the above is: - art you made, DID NOT TRACE, and is properly credited. - art you have explicit permission to use and is properly credited.
3. Human images are not allowed. Silhouettes, yes. Identifiable features, no.
4. Must be credited to wherever you got it from or referenced from. A linkback to the original image is recommended. Examples include "#1234 on Wolfplay", "Username on Deviantart". [Click to read Art Crediting Rules]
For more info, review the stickies linked above and in the [Artwork Board].
If you do not know what a stock image is, or how to properly use an image, then don't use one if you don't want to risk your picture being removed.
Since you are roleplaying, you can always use your words to describe your character.
It's not that it isn't allowed, it's just that you can't directly link to a dA image. You have to upload said image to one of the listed image hosting sites, otherwise it would be hotlinking which is against the rules.
