I take it this is an observitory? If so I recommend you change the gradient so that the upper half of the picture is black or dark blue… in order to give the illusion of hieght.
Actually, having a character in the forground also crossed my mind as a way to complete this scene. But I shooed the thought away as my character modelling leaves a lot to be desired. Must seriously look into that.
TGinn:
Will try the gradient suggestion. It’s quite a surreal setting, so little touches like that are bound be helpful in adding some realism. Thanks for the suggestion.
