My initial thought on this piece was the sheer brilliance that you have included, the colours and the softness in the light, the peacefulness that you feel just by looking at such a powerful scene. The amazing blue within the 'Wormhole' that you have constructed is just powerful, it gives off quite a strong feeling just imagining the complete scale of this scene. The close planet take on the dominant light, as well as the distant planet(s).
The Wormhole may not look accurate, but it's your own vision, which means your own originality. This piece is amazing, it captures the pure beauty of space, through your own conception.
Great piece, looking forward to seeing more from you!
Although I'm not even sure what a wormhole should resemble or look like, this picture has given me an interesting and beautiful idea on what they could look like. I really enjoy this picture! I even had a dream about a wormhole very similar to this last night. (:
