ey frame one. diagram of what each part would be when comparing to a human hand. when drawing it is very helpful to refer to your own body to see which way your leg/arm is bending. i'll get into that in another project. bones should probably be straight, so use the straight line tool when drawing the skeleton of the sketch. frame two. this is generally where i join the wing membrane to the body. if you can't tell from my very busy picture, it's around where the ball of the hip is. consider this when making walk/run/fly cycles or even drawing in dynamic poses, because where the membrane connects to the body will change, and the line will bend. frame three: the wing membrane will not have any looseness when completely extended, it will be almost but not quite straight in between the 'fingers'. this is a terrible example of the length of the 'fingers'. look at a bat or a bird for what shape you want your wing to be. frame four: the wing membrane should be loose when the wing is relaxed. this image is an embarrassment to my family name. to get an idea of what this would look like, put fabric or tissue paper and stretch it taut across your extended hand. tape it and then relax your hand. it should resemble something like this. possibly search up bats in a resting position for more reference. this is probably a better read https://monikazagrobelna.com/2019/08/23/sketchbook-original-how-to-draw-wings/ i saw that you also need help with other facets of drawing, if you are drawing animals, check out the person i linked above, she has some really helpful posts. i'll link a few more for good measure: https://monikazagrobelna.com/2019/07/24/sketchbook-original-how-to-draw-cats/ https://monikazagrobelna.com/2019/08/01/sketchbook-original-how-to-draw-dogs/ https://monikazagrobelna.com/2019/07/26/sketchbook-original-how-to-draw-wolves/ do with these what you will.
