Not that I'm necessarily in any position to critique you, but:

One of the issues seems to be distance. Perspective isn't just up or down, but also how close the 'camera' is so to speak. In that piece you linked, she looks far away. But the farther away you get, the less 'upward' perspective you can get (which is what I think you want). Maybe try angling the 'camera' / 4th wall perspective closer to your subject?

I think the arm in the distance is a bit too long from the elbow to the paw... maybe shortening the forearm or the wrist a bit more...

the only problem I see is in the legs :) Make them a bit shorter and make the lower part (tibia+foot) thinner and smaller. From this point of view nearly only the fingers of the feets should be visible. oh and the femurs are longer then tibias (even if they are mostly hidden by the skirt XD)
Try this way :D

I can try... Though I'm pretty sure you'd be the one redlining my stuff ;)

Here you go! I hope it helps... as someone pointed out, the only issue I can see is the legs~

This is funny, i was going to ask you for your help with a redline yesterday but felt so embarrassed and bothersome that i didn't ask. I dunno, still have problems reaching out to my peers.

Hay there, I believe the problem is the legs - you got great perspective on the upper body but the legs reflect a straight on perspective. I got a couple things here, the first is slight edits to the legs you have and if you wanted to perspective further I drew legs positioned more under the body in the second. http://screencast.com/t/UsQf5sVwnHl The actual way the legs are stretched out would depend on your preference. Hope this helped <3

I see the problem being in the legs as well, but the solution I see is to make the thighs cover more of the lower leg. (Like, looking down at your own legs; the thigh and knee when viewed at the correct angle cover most of the foot/lower shin. Like, her feet could be just below where her knees currently are, instead of way down where they are now.

I'd redline it but unfortunately I can't spare the time right this moment!

Best of luck;

If you have clip studio it has built in 3D pose dolls you can use to help with this sort of thing.

It's the right leg :o the right arm is shrinking from distance but the right leg almost seems bigger than the left leg. Maybe try sizing it down and angling it a little more outward :3

I don'i think the left arm is far enough away for that much size difference.
Agreed that there would be a difference, maybe working at higher resolution would help to more easily make the difference smaller.
Love the direction this piece is moving in.
