I don't know about you, but I think a human transforming into a vehicle would be pretty painful. :P
Great work on the lineart as well as the shading, working with such a huge size must have taken quite a while. I'm also impressed with the hair details, the lines don't crash into each other and each strand has it's own shading
The only thing that I can point out is the very small piece of shine on the right leg (her left).
I'm no expert on shading, but I think removing that small glimmer from an area that is currently dark would make the lighting match the rest of the light source.

Excellent work! :P

This is a magnificent drawing!

cute

What would happen if transformers was made in Japan, and they didn't take the overused mechs with giant swords and guns route.

Boobs are way to big!! Lol jk
