Each artists have their own design, and the first two pictures have very similar humanization design. The style is also the same, they just look different because of different line art style and shading (the first one used cel shading). I saw all of his stuff, his human design is very consistent, and so is the style for most of the pictures. The only difference is how much rendering he put into each picture.
I like this artist a lot. His style is somewhat like semehammer, but with more lesbian. Good shipping humanized artist is rare.
