You have a good outline which can be worked on.

At the top of the red part, you have a top part so its appears 3D, which means you need to also do the same for the top of the M.

Anyways, as i said above your outlines are good, you just need to work on your colouring, try not to buttonise like you have done here. And dont forget the direction of the light source, makes a big difference in artwork.
