Neil Bohr put forward atomic theory not the model, but his theory failed to explain 1- structure of complicated atoms having 'p' 'd' or 'f' orbitals, 2- fine structure of line spectra 3- arrangement of electrons in atoms having atomic no 5 or more.

Bohr did not model the atom. He modeled the Hydrogen Atom. If you extend his model to other atoms, you will have serious problems. The electron orbiting the hydrogen nucleus uses the S shell. Then the electron is excited and jumps to other levels and drops back to the resting level. This pattern only applies to Hydrogen and Helium. When you get to Lithium You add the P shell. That complicates matters immensly. With carbon, you have all sorts of sp reactions that have little to do with Bohr's model. As elements get heavier, Bohr's model applies less as atoms gain shells.

1-He failed to explain the line spectrum of any element except hydrogen.

2-He used the electron as material particle and didn't consider its wave motion.

3-He said that its possible to determine both the speed and the location of an electron at the same time and this is practically impossible.

How did Niels Bohr's model of the atom different from Rutherford model?

first the positive and negative charges are separated on the models and technically speaking, niels bohrs is more advanced and more accurate. Bohr's atomic model was based on quantisation of energy and angular momentum of the electron whereas Rutherford does not give an idea of permitted orbits.
