Like number 17 and 15. May need some color though. Perhaps the reflections are blue as in water? Other colors can be brought in as well.
For number 17, maybe the "O" in Mikol shows more of the "O", like in 15, but with less "rays" of the sun. Too many rays are a little distracting to me.
#51 and #52 update work. Thank you for interested on my design. I hope I can maximize my ability on your contest. Please don't hesitate to give any comments and ideas for me understanding your vision better. Anyway, sometimes I just submit design without any explanation words, its because English is not my first language so I use my effort to speak English just as much effort as I use to create design itself. I hope you don't mind.
#51 I think the cattail for the "i" obscures it a bit. I don't have the name recognition and am not sure people will realize it says "Mikol". I like cattail, maybe it needs to be to the left. I'd like to bring in animals somehow.
