im not a member, so i cant write a critique.
i still feel like you might want to darken some of your darks a bit, to make it pop more. it still feels a little bt flat. it feels like its nothing but middle tones. but that could be what youre going for, i dont know. also, possibly vary your line quality a bit more? not just more thicker and thinner lines, but perhaps darker and lghter line? i dont know if yu just coloured the sketch, so you couldnt do this, but maybe next time use different colours for lines, that helps with getting rid of that flatness.
as with any critique, if this offends, im sorry. it wasnt my intention to offend.
