The subtlety of colours is beautiful in this picture! There seems to be such a great harmony and balance, it is a truly peaceful sight The stars make the piece look very detailed, as well, and I really enjoy how you gave some stars a different shape and thus more focus. That really helps to balance the picture.
Looks great. Love the nebula, good variations and tones, blends well together.
2 things tho. The typo used I don't think adds anything to the image, rather the other way around. The big font-style there ruins it for me. Now I don't know if that's since I like the more clean ones but just to have that font makes it throw negative vibes over teh image .
If the planets had some more soft shading they'd be more 3D also blend more properly together with the rest of the image.
Besides my crit here I love the piece, great work man, nice to se things from you again, was a while agoe since last!
i thought whats wrong with you... long time nothing new but this one is great, i love colors, and background is avesome really, just you could show us more from that textures of planet... you could maybe set a little bit lower opacity of shadow... also i suppose you could bit erase that glow on planets, especially on small one... i think that glow should go over half of planet
