This is pretty cool, but something that would make it cooler is a much darker shadow.
Take a look at this picture of mars:
See how it's almost completely black where the sun don't shine? I think your cool molten scar would pop out twice as much if you made the planet almost disappear into the darkness of space on that bottom right edge.
Also, some mountains or craters in the larger planet would definitely add a touch of coolness.
The stars are a little neglected here too, what you should keep in mind is that there are millions of different stars of varying brightness in any particular direction in space. Perhaps if you added some light and dark gray pixels instead of only white ones for the stars, you'd have a better balance between foreground and background.
And, I don't mean to take my constructive criticism too far, but a lens flare on the sun would be awesome. I know that's really hard to do with pixel art, but it would be kick ass nonetheless.
Good drawing. I liked the debris between the two planets-- but the magma was my favorite.
First off, thanks for the review! It's great to hear from the more experienced.
Ah, yes, I see what you mean about the shadow! That's certainly something to keep in mind, especially because I'm too lazy to go and fix this one. As for the mountain and/or crater idea, I tried that and failed massively when trying to do that. On the stars, I had no idea that a noise field could be used back when I made this.
Holy crap I wish i could do lens flare like that. . . That would look kick ass, you're right.
(And can you believe that the magma was actually an after thought after grabbing the wrong color from my palette?)
