This one bears a similarity to your Alpha Vespae piece which I critiqued earlier. fav.me/d5phebw This one has several more elements to take into consideration. First off I applaud you for adding three satellites to the ringed planet; one would have been plain and two would have been too symmetrical with the binary system. A comment here mentioned the rings being too transparent, and I agree and disagree. Planetary rings are made up of rocky debris and gas, so they WOULD reflect the light from the stars, but they absolutely can appear to be ephemeral (as the Cassini probe has shown us with its astounding high-res photos of Saturn). However, it would be very unusual for the entire ring system to appear uniformly, especially in this variable light situation. Where there is shadow, the rings would disappear, and where there is light, the rings would glow- stronger towards the light source, and fading out into thin lines near the shadow terminus. My only other comment is on adding more dynamic features. A system this crowded would have some pretty spectacular interactions. As it is, it seems fairly static. A minor addition could be interaction of the planet's magnetosphere with one or more of the satellites, like an aurora, or even an exchange of gaseous atmosphere. Some planets are also volcanically active, whole or in part - and remember that volcanoes may erupt with materials other than hot lava. Again, good work! I love the hints of detail on the planet's surface.
