@joojaa - I agree 110% with @Vincent on the first draft. For the second.. eh.. I might still make 9,8,7 arrows a tad more vertical and move everything left a bit more. I'm not a fan of the typeface for the legend, but that's just shear preference. I kind of also think a bit of line weight variation may help overall... i.e. make the arrows, circles and legend paths 2x the line weight of the drawing (again, just my preference)
I'd actually prefer the schematic to be thicker, but given its detail I suspect that's problematic. Having a bit of line variation would help separate the schematic from the legend visually.
I would also align the left edge of the legend with the right edge of that big quote mark. And make the 8 centered on the legends left edge (so it's a visual vertical between all 3)
I think if you make the 7,8,9 slightly more vertical you can center align the 9 on the left edge of the quote, then the 8 centered on the left edge of the legend. ...just oh so subtle alignments that add cohesiveness overall.
really just nitpicking though. Nice work!
