I think you forgot to replace the greys. Ah I couldn't resist.
But err, the HQ tag is not defined by just the clean if you ask me and lots of people have their own view on things, like... Bad TL + awesome clean = HQ ? good TL + terrible clean = HQ? SFX to english y/n = HQ? Bad TL + good clean + awesome TS = HQ? Good TL + Terrible proofread + awesome clean + Terrible TS = HQ? Black 0 0 0 and white 255 255 255 = HQ? and we can go on for a while. So we've to know what YOUR HQ is, what typesetting style you use, of course I know what you mean. I'm just saying HQ's something personal.
And it looks like there's dust between panel 1 and 2, in panel 4 on the right it might be dust too, you might've slightly overlevelled... To know that we need to see the raw.
