Something that I've noticed in the furry community is that there are tons of different ways that people draw their bat-species sonas' wings. So here I've made a little compendium of most of the different styles I've seen out in the wild!

"The Glider"
Use of hands in casual daily life is put above the use of the wings in anthropomorphic evolution, and such disuse caused the fingers and wing's webbing to shrink to maximize the abilities of the hands above that of the wings. Small amounts of webbing sometimes found between the fingers of the bat (recessive trait) as a remainder of the days when their wings were once used more frequently.
Wings of this type are closer to that of a sugar glider or flying squirrel in terms of its abilities; as the wingspan's surface area is so small compared to the rest of the body, these wings cannot be used for actual flight and can only be used at most for gliding from point to point. Clothing must be made with open sides to accommodate the webbing attached to the sides of the body.

"The Extension"
Use of hands is important to those with these types of wings, but the use of wings is also equally important. Equal importance between both elements caused the growth of thin muscular appendages to support the full-size webbing of the wingspan. One of these appendages is located at the back of the wrist and can be flexed out or held out to open the wing fully.
Use of these appendages in the design of the wings create a classic dragon-shape in the wing's webbing. Number of appendage protrusions at the elbow can vary, and can even be omitted altogether for a sleeker appearance. Clothing must be made with open sides to accommodate the webbing attached to the sides of the body.

"The Minimalist"
Mixed use of wings and hands caused wings to remain semi-developed, with webbing shrinking to either the elbow or armpit area. Commonly found in coastal family lines, or in family lines of fishers, swimmers, and/or surfers. Often considered the "modern" wings, Thumbs remain unwebbed to allow for usage of hands.
These wings are, unfortunately, the poorest at both gliding and flight due to their incomplete webbing attachment to the body. Their main airborne usage comes from use as natural parachutes to cushion falls. The best use of these wings comes in swimming; wide handspans can cup great amounts of water and make for excellent propellers in the water. Clothing does not need to be specially made as webbing stops at the elbow/armpit area and does not make contact with the sides of the body.

"The Classic"
Extreme use of wings over hands allowed wings to stay fairly the same in anthromorphis as they were seen in feral ancestors. Forefinger and thumb may be extended and/or webbed depending on the amount of use the hands typically receive; unwebbed and shorter thumbs/forefingers mean more hand-mobility whereas extended and/or webbed thumbs/forefingers allow for greater flight mobility and speed.
Considered the best in terms of flight ability. Clothing must be made with open sides to accommodate the webbing attached to the sides of the body.

"The Draconic"
Unknown origin, theorized to come from ancient, mystic, or partially draconic (dragon) bloodlines. Wings protrude from the back of the bearer rather than their normal arms. Wings can vary in size, though commonly the arm length is usually the same as the regular arm's length. Wings separate from arms allow full unhindered usage of hands and arms, and can even be used as an extra set of arms for carrying certain objects.
Considered on par with "The Classic" in terms of flight ability. Anatomically speaking, these sets of wings also mean that the bearer has two sets of pectoral muscles in order to accommodate their inclusion. These pectoral muscles would likely appear beneath the main set that control the arms of the bat in question. Clothing must be made with open backs in order to accommodate the wings' rear protrusions as well as their accompanied webbing.
