Vast improvement in  a very short time! I am impressed! I am afraid that I have great difficulty in givu=ing  a good critique as all my training comes from a more traditional background. One thing that I ALWAYS do is to change the textures - I dont care for the way the usually come with a very few exceptions- I use the material room alot- I have a theater background so I tend to light the scenr like a set - Typically high right -high left and a back light ( in theater this is known as a chicken foot) Then I look to see if any of the objects in the room are casting light  or are reflecting light and add those lights. I can't really comment on the charecter as I know nothing about transexuals - I assume the breast are real? Breasts should hang from the body - think of the anatomy of breast tissue , maybe a different top would help this as the bandeau thing just looks wrong - His "package looks like a dance belt there is an anatomical structure under there- I would recommend trying this with a pair of jeans and a tee shirt to see if the charecter looks like a she-male - if it does with the clothing on then you can always lose clothing - i would adress the shin texture too - very pink orange and no freckles or spots - imperfections will help you pull this illusion off. Sorry I cant be of more help but this is kinda out of my range.- good luck
