Please refrain to use the word "ugly" when somebody is posting something on the dev section, I personally don't care and understand your point but somebody else could take it pretty badly to spend some times on something and to receive this kind of answer.
I think I will use the 4th icon as the base for the final one, I need something that looks good when rescaled to 64*64 so I will have to reduce the width of the flame to make the "M" stands out a bit more.
Thanks for all of the feedback! I will try to post a more final concept soon.
