Is it just me or did you only add the dots ? I think thats the actual background with just dots D: Did you remake the whole thing or did you just add those bubles?
i edited the trajan pro font myself to mimic the GoT logo and even turned it into a brush, the background and scratch texture i found online[not hereaand its the actual GoT background/textures]and yes i added the bokeh and a few diff color filters
