Hello,
I would move the tanks up a little bit, shorten the bungees so that the valves turn more (your upper bungee loop seems to be caught by a loop or something), the tanks a little bit high at the butt for my taste. Not trim related comments: put your SPG back in place after checking, shorten the attachment of your longhouse reg. The video was too short to judge for certain, but you seem to swing along your body when you kick (head/upper body down, kick, head/upper body up, glide). Try looking forward when kicking. This was a modified frog kick.
Im sum, looks really nice already, just the last few percent to perfection.
cheers Jens
