Thanks for the comprehensive response to my observations; I harken back to what I said "be careful when drawing a dark line and dotting both sides". I was simply pointing out that, to me, the line stands out and does not look part of the form of the lips. Had you not told me it was line art, I honestly wouldn't have known; due to not knowing prior, what, exactly, that line was trying to communicate to me was unclear.
My line of thinking doesn't just apply to photo-realism; believeable stylized artworks still rely on the principles of realism.
Ah I see, I genuinely did not know, so I appreciate you explaining that to me and how it works.
Thanks for taking the time to consider my critique; I genuinely enjoy bouncing ideas around with others and diving into a dialogue regarding each others work and journeys.
Whether the critique is of use to you or not is by the by, that's the beauty of being able to select what you want to use and what you will disregard. As long as I engage with the community and offer constructive thoughts and encouragement where I can, I'll feel like I am doing my bit.
That said, keep up the good work, looking forward to seeing more
