Should be a bit better now. The idea was for it to be heart-monitor lines that went flat after the heart burst through his outline.

Thanks for the crit!

Yep, already lots better. Nevertheless, there is e.g. far too much AA at the shoulder, the line seems to be thicker than the other ones. These whatchamacallit-lines on the left of the image on the other hand might need some more AA.

Ahh, I see. I'll definitely keep that in mind from now on.

Thanks!

Try not using such bright colors to AA the white. You may want the AA colors closer to the black than the white. 

Reposted with changes to the anti-aliasing and cleaned up the lineart a little.

Which areas are particularly bad on the AA? Or is it generally not being used correctly? Thanks!

Voted no, as I think that the outlines and the AA need some more work..
