Hey vdeny, thank for the effort. Things I like: 1) Like the realistic looking rider/bicycle (although the winning design doesn't necessarily have to have that); 2) Like the use of the Jamaican flag in the X.
Things I don't like as much: 1) Not crazy about the glossy semi-circle running through the logo. Should probably be flat. Not sure if I'm using the proper vocabulary... 2) Would hope that the font of the B and M could be closer to the "font" of the X while still retaining its flag status 3) The chunk of white in the middle of the tire. No idea how you could change that.
