Horsehead nebula if i'm not mistaken...shows you how much i whore that stock. Speaking of which it repeats at one point and you can see the two dark marks which is a lil distracting. Mixed on this one, the colours are good, the C4D in the top left doesn't fit with the other used i think. Pleasing though its a vibrant sig. KIU.
And Ali, borders can constrain an image, plus a border has to fit with the style of the image. Not thats always the case, mind.
