I think as a style it's really beautiful, but because you asked about lighting I will say it's a bit off. Space is really difficult to shade (as we have never seen it first hand to understand it) because light is coming from everywhere. The stars and bouncing off the meteors/planets. But I would say that the light is mainly coming from that large star behind the ship. Therefore the side we see is going to be dark. The top fin of the craft is going to cast a shadow along the back end diagonally and the fin itself would be very dark since none of the light is hitting it (assuming there are no stars behind the "camera"/viewer)
