She has lovely eyes for sure.
And done in awesome detail!

Gentle, sketchy, and yet subtle & nicely done shading. Really nice, especially on the legs and arms.
That pose, eyes.. and glare of hers. So sweet and lovely, yet predatory~ She's so beautiful <3

Bad at keeping it loose and fast? What, was it difficult for you to make and/or took longer than you would like?
Well, it takes me 'quite long' to make a good sketch/lineart/traditinal or digital drawing, and even tho You have a lot more practice & skills, you shouldn't rush too much. *hugs? xd*

No, when I warm up I try and do posing and detail really sketchy and focus more on gesture lines and such but I'm so ingrained to sit and work a picture start to finish out the gate I'll refine and refine and refine. Been trying to use warm ups to loosen the brain and work on anatomy.

Makes sense. I'm not sure what more/else to say, I'm feeling you heh.
