I Like to keep my tutorials clean and more step-by-step like, so here are some tips I didn't put on the picture!
1. The shape.
- Have you noticed how most of the kuroshitsuji male eyes are sharp with a lot of edges while female eyes are soft and round? Grell's are neither! They have a little bit of sharpness but the shape is mostly round, more like an almond actually. This adds to his feminine looks.
2. Grell's Eyebrows
- Even though Grell smiles, his eyebrows are always bent as if he's concerned or sad. This, along with the sharp teeth, are Grell-signatures, and remembering to draw these things will help your character look like Grell.
3. Grell <3 False Lashes
- Go crazy with the lashes! As seen in the anime, Grell likes to wear make-up and false eyelashes, so go ahead and make the lines a little thicker and add a lot of lashes!
4. The glasses
- Grell's glasses are NOT rectangular, but slightly triangular. Remember to draw the little "holder"-things at the nose. The frames do NOT connect with the middle or the bottom of the glasses, but almost at the top. To add glass to the glasses you can put a thin layer of white with the Airbrush. Don't forget to add the little charm he wears on his glasses.
I use Paint tool SAI, but you should be able to recreate these steps in any programme.
