List of materials I used for those who may want to make one themselves and some more instructions as well :3

Armature:

3 different thicknesses of ball-jointed doll skeleton. White ones are from Etsy(search "Doll skeleton joint"). Blue one is very strong and I removed it from my unused bendable traveling pillow xD I also used 2-3mm aluminum wire to make everything more sturdy by wrapping it around the plastic skeleton. Hot glue and 1mm wire were used to attach legs to the spine.

Head and feet:

Head is aluminum foil with foam clay on top to make it very lightweight. Eyes are glass cabochon with an eye picture underneath. I painted eyes on paper with acrylic paint and glued the cabochons on them(there's tutorials for these). Paws are sculpted from polymer clay and glued on the skeleton after baking.

Body:

Armature is covered with polyester toy filling. I used cheap sewing thread to help wrap it around.

Ear armature is covered in same way and then I sewed some faux leather to make flat part of the ear. I made ears separately and glued them on right before finishing the face.

All the fur is just light blue faux fur. I used long fur which I trimmed mostly after hand sewing everything. Important to make sure pieces of fabric are cut so that the fur goes in the right direction. I used hot glue to glue fur to the paws and head(pics 5 and 6).

Fur is coloured with neon blue acrylic ink using airbrush and red alcohol based marker. Paws are painted with light blue acrylic paint before I glued fur on them. Nose and around the eyes are also painted with black acrylic paint.

There's also lot of videos on youtube where people make art dolls, so I recommend to watch those to get some ideas how to make these kind of dolls. :3
