Artist:Ohmudak should be ok. I don’t see anything indicating that they mind edits when they are properly credited, and is not similar to anything on their Patreon.
Artist:Spectre-Z on the other hand might not be ok. They have left several edits here, but they also have taken down several edits, including some recent - especially ones that were too close to what they had for Patreon. I would suggest that you get their permission first. You might be able to reach them via a PM here, although it might take a while for them to reply.
