if you whant bit collor to your backround sig (if you use photoshop) duplicate your render so much times it fits the hole background add motion blur angel 45 and distence 50 is a example and set layer mode to collor then you have a better collor background
if you want to blend render more in to it
duplicate the render 3 times hold them on the same place
hide the 2 uppers layers take your lowest render go to filter > blur > motion blur set angel to 45 and distance 26
unhide 2nd render let it why he is
unhide 3th render and go to filter > blur > guasion blur set distance to 4 and layer mode to overlay and opcaty 40-60 what you like the most
i hope you understand what i mean
but nice for first sig
