Bridge the gap - Retopology I am doing retopolgy on a sculpt. But while doing this I ran into a problem. Please refer to the picture below



The region I marked with blue marker contains more vertex and the region I marked with red marker contains less vertex. So how to fill the gap in between? I naturally don't want to populate the region I marked with red marker with more vertex. So how to bridge the gap?
This is one way to reduce vertex count.
