#18 - This is very slick, this kicker is a nice balance between stylized and recognizable.
# 17 - This seems too busy. I have to admit, I don't know of any particular significance/symbology to the gate pictured. Because I don't know what its significance is, it seems out of place.
Thank you for your efforts so far. I will post more after sleeping a bit. I am also making a general comment regarding the Umyang (annd the use of red and blue) before I go to sleep.
#41 - I really like that, while being constrained with the presence of the Umyang, you've incorporated a very obvious river into the mix. I was worried about the use of gradients, but I believe I can work with these to the extent you've used them.
#40 - My backup choice if I can't handle the gradients that you've used when it comes to working with my printers.
#38 - I don't like the darker blue, compared to #40.
#57, #58, #59 - The kicker being larger is nice, but I don't think I like the expense it costs the Umyang. I like the yellow in #58, I may feel differently about its placement after I've had a chance to sleep on it.
With and without gradients will be fine - please note that my first pick is #68. Thank you for the work you've done here - I am particularly drawn to the contoured river that matches the kicker's leg. The two fitting together makes this logo stand out from the rest of the pack.
