Pup move WIP -- CRITIQUE WANTED

Popis

So a little WIP of one of the many parts of my next 'advanced' animation. Ultrasounds and beating hearts are nothing new to me, but I tried making the color more realistic and adding visible bones (all anatomically accurate and placed) It is to scale with the rest of the project, so it's size will not be changed. How do you think it came out? What do you like? Dislike? How to improve it?
