Better pics would help a lot. Take your pics standing in front of a white wall, with bright, direct (ie, not overhead) illumination, and turn the camera’s flash on. No filters.
Will such pics be unflattering? You betcha–but then, the point is to elicit helpful feedback about the status of your physique, not to impress anyone. (The time to impress is with your contest pics.) Much more importantly, such pics will be revealing–you can’t hide flaws or fat in them.
So, no more pics half (or more) in shadow. Face the light, and face the music. In the long run, you’ll be happy you did.
