Overall, this is very solid and I liked it.
At the beginning, the strings sound a little strange, and the texture feels a little muddy overall. I liked the switch to the new instruments as while lots of elements changed, it still transitioned nicely. I enjoyed the next section too, and while it was somewhat dragging on for a while, I think it's fine because I felt the piece building the whole time. The switch at the climax (2:10) was a bit abrupt, but I don't mind it. Overall, I really liked the way you incorpated the theme by taking inspiration from the source material and shifting it as the piece progresses to fit the "Old meets New" aspect.
