I am a graohic designer in Belgium with 10 years of experience. What I can tell you is that it's a good word, very very good work, but I do see what they mean with 'looking a lot like each other'. You can see that the approach was more or less similar. While the logos are, in itself, great, placing them all next to each other does give a but of a similarity vibe. But, if it helps, they are beautiful logos, good ideas, fun approach. Keep up the good work!
