Omg I love Lackadaisy.. I stalk the DA and comic. But from my experience I can tell you what I normally do to try to change styles or make a new one. I'll take images as references like the one you have there and try to draw the faces. Once your sort of comfortable at drawing them try to change them up or apply them to your own characters even. I dunno this is just what I do, I'm working on a similar style because I want more freedom with expressions an poses than my previous styles gave.

>.<: hope it helped any.. if at all.

Oh and if you are struggling really badly with trying to copy a expression trace it once or twice and try to pick out shapes or some way you can get your brain to grasp how to do a pose or expression. Afterwards you can try to draw it yourself (sometimes it helps to trace a image to get rid of all of the distracting details to help your mind pick out shapes and such to draw easier).
