Whoa that looks amazing! Really impressive! You deserve way more credit than you're getting.
But for some criticism, it's still kindof vague what it actually transforms into. It could be a mecha of some sort, but it has no legs or any other way of movement, or a clear head.
The cannons pointing in random directions also seems kindof pointless as they don't seem to have another function than shooting.
But heck, you made this thing in just a week, I wouldn't even know where to start! What software do you use to make these animations anyway?
Looking forward to your next submission, keep up the good work.
