It's allway's a pleasure viewing your work and though i love the alteration's made to the foreground artwork, i prefer the dark space background of the original piece, Tobias, because it has the much stronger look and depth of real space. Space is an unkind, dangerous and eerie looking place but this version is far too soft and gentle in its appearance. I also think that there is way too much light/glow at the left, as you would never see it that bright in actual space itself (though this is sci-fi and an artist's own visional work of imagination; which rarely portray's total/actual reality), and therefore takes away a great deal of the realism of the piece for me. Mind you! The way you have done the lighting effect is brilliant, as are the stars and satelites. I think the planet's blue's and brown's need to be a darker and stronger colour to bring it more to the forefront of the viewer's view, and thus showing a distinct distance between the foreground and the celestial background.
Gorgeous. I love the use of contrasting warm and cool colors here to keep the eye moving around - from the warm highlight in the left-hand side of the picture, to the blue comet, to the pops of orange fire from the impacts on the planet.
Impressive work. Granted, your work is always impressive, but the details on this are incredible. This is kind of a scary view of the future, although I fear we are headed that way. At least in this version of the future it looks like we're improving our abilities to survive in space, instead of being entirely stuck on a planet that looks a bit hostile.
Regarding the picture though, I love the effects on the comet, and the lighting that you used here is stunning, especially the fluctuation lines in the upper atmosphere/magnetosphere. I don't think there is actually enough matter in the space around the earth to make the region closer to the sun that much lighter, but this is why it's art, because it looks amazing and it enhances the understanding and feeling of the piece even if it slightly departs from physical realities. Awesome job all around.
