This is a submission of design for 
The Concept
Kuya is somewhat similar to the Korean's Oppa or Malaysia's Abang, which is a to call the elder males by the younger males and females (Oppa only applies to female calling to elder male).
Also did some research on how the Philippines use 'Kuya' in their daily life. Source
From all these studies, I can see that Kuya portrays an image of the bright and friendly guy, helping others selflessly. Just like what Kuyabot intended to. Then, I observed the Philippines flag, the golden sun is the right fit to resemble such message. Hence, the concept of mine to design the Kuyabot is to create a bright and friendly guy like the golden sun of Philippines, literally.
Design components:
The color scheme will be based on the Philippines National Flag color code.
The Golden Sun from the flag.
