NOTE: We want something integrated with the Letter "U". We no longer want the word "underdog" or "training" in the logo. We want a logo that represents someone being an underdog or overcoming great odds. Please note that this doesn't mean we aren't considering anyone who has submitted something with those words in it, it just means we are placing more emphasis on integrating the concept of an underdog with the letter "U". Also, please note the design reference and inspiration are simply guidance, we don't want you to simply just repurpose those, we want you to be super creative and give us something amazing! We don't require that it has anything to do with the images or reference in guidance or inspiration.
The logo has to be mean, clean, motivational, uplifting and convey a sense of purpose, dedication and perserverance for anyone that wears it or sees it. They should have pride in wearing it.
The three keys are contrast, legibility, and uniqueness. Is it unique? We must have never seen this before. Is there contrast? The initial design can be two colors, but we will most likely ask you to integrate a third like red. Is it legible? It is important it's easy to put on clothing and that users recognize it immediate and connect with what it stands for as soon as they see it. If it has too much detail it might be difficult to recall or reference.
