Letter M App Icon, Modern Lettermark Logo Design

After a long time, I've uploaded a shot in dribbble. I was too busy with my job. I've designed this lettermark app icon keeping in mind that I have to keep it too simple & gentle.
Also I wanted it to look a bit formal.

Feel free to give your valuable feedback.
Thanks in advance.
