You can but this doesn't really blend your render well. It just gets the BG's colours, but it will kinda mess up the render. You can duplicate your render, select the first layer [not the copy], and blurr it within a range of 10-30 PX. The text should be way simpler, just make an 16 PX text [simpel font] and lower opacity [Choose white, grey, or black as forground colour when typing]. Also, yeah a glowing board is a good trick, but it's not really fitting the sig. I'd say just remove that lol. Indeed you used too much black tho, you could have made the colours stand out more 'cause of the bright render. You can do this by making a new layer above your colours' layer, filling it with white, set it to Overlay/Soft light. Then you can lower the Opacity if the colours are too extreme. Keden.
