Less is definitely more, especially for smaller body parts.

Bicep size in relation to the rest of your body is to some extent genetic - some guys just have big arms and some don't. It also depends on the shape of your biceps and length of your arms as to how big they look. Someone with 17" biceps but long arms may not look as big as someone with 15s but much smaller length (comparatively) arms.
