I normally don't like the Live action Movie designs because their a bit ostentatious, but I got to say this is real creative and inspiring. He looks like the original character and has a lot of aesthetics to his design. Same with your Strika. Good Job.
You have no idea how much I want to see this in a movie. The Apache is my favorite military vehicle ever and seeing one of my favorite Transformers ever as one is AWESOME. I love how you incorporated his Beast Machines design into it. ^__^
One of my best friends had a request for me to draw an Apache Decepticon, so I did. Later on I decided to call him Obsidian, and you've given your view of Obsidian the Apache as the alt mode too! Coincidence! There is a difference, though. I drew the rotor as the leg-thingy.
