I highly recommend you install Expired's RaceMenu mod to drastically improve the character creation menu both in terms of usability and customisation.
Recommended mods for Creating Realistic & Unique Female Characters in Skyrim
Body & Skin:
First, to improve the shape of the default female body install Caliente's Beautiful Bodies Edition – CBBE – . You can choose either a slim body or curvy body during install. You can see the curvy option in the first picture.
Next, for the skin texture I recommend installing SG Female Textures Renewal
Optionally, you can add some sexy looking sweat to your sexy new body by using Sporty Sexy Sweat – wet body skin texture – CBBE UNP UNPB ADEC Vanilla
For a hair pack you can install KS Hairdos – Renewal
Eyes & Brows:
There aren't many eye textures to choose from in the default game so next add The Eyes Of Beauty to your game. This mod will give you loads more high resolution eye textures to choose from.
For the eyebrows I recommend Brows
If you want to go into a bit more detail you could also add some cute freckles to your character using Freckle Mania
In the default game the warpaint and dirt looks blocky and low res so install XCE – Warpaint and Dirt . The main file and the optional beast tints will do that.
Note: For the warpaints to show up properly on your character, you'll need to add the line iTintTextureResolution=2048 to your SKSE.ini file.
And one final, absolutely essential mod to make your female character beautiful is tktk's Face Light. It adds a spell that lights up the face which makes it look so much prettier. I also recommend Gunder's Face Light add-on Face Light Plus
