A little advice if you are new to deviantART.

If you are not a member of deviantART you can join easily and it's free.

Once you are a DA member you can then upload your deviations and apply to be a member of this group.

When each Art piece has finished uploading, you are able to skip the part where you offer your work for purchase if you wish, just click at the top show my deviation, or back to your profile.

While submitting Art to the website, you may wish to untick the box  "allow full download of this image"

You are able to edit almost everything fully later. e.g  The title of your work.

After joining the group and uploading your Art,  you are then able to submit your Cosplay Deviations to the group so that they can be displayed in the Featured Gallery and other Gallery Folders!

Each of your deviations will then also show "featured in xyz Group" when you click on them.

Good luck.
