I don't think the "wave" is communicating "river". I do like the warmth of the sun contrasted with the blue of the river, but all the colors could be more vibrant. I would prefer a more teal (aqua) color incorporated into the logo. I like the type face for the word "River". Thank you!
Illusion, I really like the simplicity of this mark! I am not sure it reads "church" though...although it reads "river". I like also how River Community are the same size/weight. Can you push it a bit more--keeping the simplicity of a singe mark so it stands alone, but still reads "church"?
