dear @radudangratian,
please keep it friendly ... if you check out his post you will learn about how he created the logo.
In my opionion there is nothing wrong approching a logo in a simple way - if you google the net you will immediately come along this concept for logos ... moreover it is a lot different to your as well.
If you think that his approch maybe fitting better then you might want to consider developing yours further... you still have time doing so
Regards
