EF recommends to lower your bucket size to 16 to help with speed and mem. I use a shading rate of .21.

Now for closeup renders, scale your figure up 1000%  This will give you better looking lashes and hair. Increase your camera focal to 100 and move it back. These are simple and common rules for closeup renders. Poser scale is very small to any other software. That is one of the main reasons that small stuff like lashes don't render as well.
