Hello! My team is currently in the production of a space exploration game and I would like to know if the style I have works! I only have a ship engine right now, but that is what the game’s art would be like.
Thanks for any opinions! 
Consider focusing on game play mechanics and systems first, before worrying about graphic.
With that out of the way - the style is simple and the piece (ship engine) is barely a relevant representation of the game theme (space exploration). Would like to at minimum an entire ship to give any quality feedback.
What you are showing is kind of like showing a characters foot and asking if the style is good for the character.
Keep at it - and work out how the game plays first. (Advice coming from a non-coding artist)
I managed to finish a ship, although, I left it on my other computer!
Will upload it tomorrow!
