# Why am I getting an error in my transfer function?

I'm trying to solve part b here, and my transfer function is coming out as $$\frac{-1.25s}{s^2 + 2.05s + 1}$$ instead of the given $$\frac{-1.25s}{s^2 + 1.6s + 1}$$. Since there were no initial conditions, I just transformed the capacitors to impedance $$\1/s\$$ and applied KCL at the node. What am I missing? My working is below as well, I can't see where the problem lies.
