I like it
So this was pretty cool, I like the style here a good texture of the planet allthough I would not have a clue what jupiter looks like I think you created a good feeling and visual on this I do think the "CANVUS" could be larger though, just an idea throwing your way.
~~THINGS TO IMPROVE ON~~
maybe you can make a larger Canvus maybe even then allow for more detail, of other things and will allow for more fin elements and more detail as mentioned, so make a larger canvus. just an idea throwing your way.
