Unfortunately deviantart doesn't support marmoset to view the painting in 360, so I gotta redirect you guys to my artstation or my facebook link to view it:
Bought Jama's 360 painting tutorial the other day and wanted to test it out using existing paintings. Figured it could be a good chance to show a scene like this with the space pirates! What a great platform to do some concept story telling, cant wait to keep trying stuffs out, hope you guys enjoy this!
Here's Jama super helpful tutorial if you're interested:
Ah... reminds me a bit of the trailers from the upcoming Mass Effect: Andromeda.
Always a treat to see your Buccaneers! Thanks for the links!!!
Also it looks like you're using a spheremap instead of a cubemap - the equator is blurry while the poles are crisp.
