It was an anti aliasing issue in Photoshop that caused the artifacts where I had previously cut/erased parts of the image. Sorted and re-uploaded now. Also used Beneton Movie Gif to make the animation as well instead of an online programme ;)

Thank you, will check it out!

There are some animation free apps in the links section and the forum's resource thread has some too.
Submitting pre scaled pixelart is not needed in Pixeljoint.
The -+ under all art is a zoom feature :)

I used an online GIF maker as I don't have any other way of doing it? I guess that may have created the artifacts? :( 

Any advise welcome

Thanks

You have a lot of artifacts in the middle frames and this might be your app settings?
