i've been trying to make a character myself for the game from Scratch, but i really don't know wich pose could produce the best results in the editor...

i tried a normal pose (similar to the robot used on the tutorial) and the clasical one with the fists raised and the legs spread up (the typical fighting pose), both with their advantages and disadvantages...

so i gotta ask you guys: What is the Best Bind pose to draw the reference to import the character into the game?! how big do you do them (do you make them big with a lot of details and then shrink the image size to fit in the game?!), how can i put transparency on Sprites to use them as references for keyframes?! (is there a transparency slider i'm missing, or do i have to import them with the transparence baked in?), and what you guys tend to do in regards to back sprites that needs to be done by hand ?! (like the back of the head or a shirt for example)
