Simply marvelous!!
A well crafted undertaking, I'm impressed.
I am quite close to declaring this the feline posterior.
I Like it!! A LOT!!
Though I have one small concern: she seems a bit nose light...
The truck front end seems a bit truncated, unfinished. With all the weight, and work, in the rear perhaps you might consider something to offset all that, a winch, or a weight rack or a plough blade?
In art, as in life, balance is as important as she is delicate...

Gotta agree with everyone else, this is good work!!
