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.
