Your tibias seem way too long.
I did almost the same lengthening as you (7.5 cm in tibias) and I was much shorter initially compared to you but still my tibias look way more proportionate to my femurs and my whole body.
Although with clothes on you'd look ok, you should have stopped at 6cm max as you should have had already tall tibias and now they are too much even for someone like me who doesn't care much about proportions.
Your arms look ok, only your tibias are too much.
