Darn, I totally forgot about your pm - sorry
In your original photo, your legs look too short compared to your torso, but they look much more proportionate in your mockup.
Your arms will appear a little short after LL, but I highly doubt that any "normal" person would ever notice.
You will be taller and have an overall better appearance
Edit: And do as Alu has said and bulk up your legs. They look like after 6 moth in a wheelchair ^^
