New to shortboards

Not sure if this is in the right place but here it goes:
I've got my mind set on a shortboard. I've been surfing foamies and longboards for 3 or 4 months. I picked it up pretty quickly so that's why I'm already looking into a shortboard. I'm 16 years old and I skimboard, wakeboard, skate, windsurf, sail, bmx... lots of stuff, so I figured it wouldn't be too difficult for me to start on a shortboard so soon. I also learn quickly. What's your opinion? Should I continue to surf foamies or move on to a shortboard?
Thanks
edit: I'm also rather small and light, disregard my username
