(Mock ups attached) Are my legs too long?

Edit Post

Hi guys, I want to go from 170 cm to 177.5 cm.
Wingspan: 174.5 cm.
Sitting height: 88.5 cm.
Jeans inseam: 30"

My first choice is probably internal femurs due to greater safety, less recovery time, and hidden scars. But I am open to tibias if my proportions look weird.

I've done mockups now, but it looks like my legs are too long even before LL? Or am I just imagining it? And which should I do, femurs or tibias?

1st picture is current height, 2nd is femur 7.5 cm, 3rd is tibia 7.5 cm.

Oh no...I was afraid of this. I'll put some mockups with my hands by my side, and me in clothes to see if that makes any difference :/

Although I'd rather be a disproportionate average guy than a proportionate short one.

Ok, I think I agree that tibias look better, but isn't it impossible (or very unadvised) to lengthen 7.5 cm on tibias? I don't think lengthening is worth it if it's less than 3 inches (just for me personally).

Am I correct in understanding tibias have more visible scars, worse recovery, and permanent knee pain?
