Very different boards.
Higher tech in the adult sized custom - sintered base instead of extruded for example, channel binding attachment instead of three holes.
However at your weight the flex of even the smallest Flying V custom (148) will be on the stiff side as you're under the recommended weight for the 148. You'll grow into the 148 and out of the 140 smalls.
Demo if you can.
