Your DIY Bike Lift looks quite good Buddy .. very tidy !
So much easier to work on the bike when it's up at that height.
I would however advise that you sort out the Strapping Down method .. that single strap hooked over the plastic Fork Protectors will not hold much if things do start to move!
Both 'sides' of the Strap need to be 'fixed' (secured as in by wrapping around the Bars, Rear foot peg hangers, Grab rail Frame or whatever) as it is ... if the bike (I mean when the bike) moves .. it will move 'inside' the strap loop. Better to use two or even better still four straps .. one or two on each side front and rear. Also close the Ratchet handles down flat. Too late when it starts to fall .. you will not catch it!
Hard to see in the picture .. but has the lift got a 'height locking pin' of some sort .. not good if the jack is the only thing holding everything up. The lift needs a locking system so that the jack can then be lowered a little to take the weight off the hydraulics.
While I'm on a roll here
It also looks like you might have just cut that nice new strap
.. tail end and Stanley Knife on the deck. Never a good thing to do that .. Sods Law Rules that you will need a longer strap for sure at some point very soon.
All the above is just in my opinion of course .. nothing more
