If it intend to look creepy, I think it is “mission accomplished”
Now for more focused critic, even though the cat seems like a fine piece of modeling it’s still lack something to look steampunk for me (like steam…)
As usual I would recommend googling for steampunk references. Observe the models and assimilate what makes them steampunkish…
On this precise example you have the steam (yay steampunk…) you have rivets (rivets where all the craze in the 19th century and early 20th).
Instead of simple articulations, I would see more complexity (think like clockwork mechanism).

Even if it’s a 1950 cat, these elements would be present. If it’s a 1870 cats, I would add copper, superfluous decorations and wood maybe…
