Somewhere between art and realism you've lost the point of "art", art isn't about being able to draw a car realistically, it's being able to draw a car realistically with a meaningful message (although I deem that an incredible feat, if you could make me cry over a car then you, my good sir, win at life)
What I'm trying to say here is all you've got are some fancy looking cars (I'm not even going to mention lack of shading or realism or whatever) you don't have a message, you're not doing anything different, this doesn't make me feel anything, I don't question what's going on in your head, I'm not trying to figure you out right now.
Besides the fact that you have no message, you also don't have much drawing skills to begin with, your anatomy when it comes to living things is wonky and strange, it's certainly no different from the pack, and I don't want to sound stereotypical, but furry usually tends to lead into anime, which tends to lead to having no artistic credibility whatsoever.
You need to learn to speak from your heart, portray what you feel, spill your insecurities onto the page. Hell, you could even get a pass at being bad if you make someone feel some real genuine emotion.
Just keep rollin with it buddy, you'll get the hang of it.
