Some personal ideas on Tartii:
You could probably taper the tail a little more. It is sort of blocky at the end.
The wing membrane should generally connect to the body at or behind the hind legs to avoid the thing some people call "hangbutt". There is a biological reason for this as with propatagium, it is mainly to do with take-off and landing control.
I notice you use 3 fingers for the wings. The default should be 4 (not including the "alula thumb" which in your case is just the little claw at the corner of the wing; I'll make a post on how this works later) but there is nothing wrong with 3, I just personally like using 4 since it gives better shape to the wing. As long as you are conscious of this it is perfectly fine.
