Congratz on being successful on shaping models.But along with that you need to improve the following the next time:-
Tights model needs to be lowered inorder to stretch the length of the body down.
You forgot to stretch the neck muscles.(Hump)
It seems accidently you somehow managed to corrupt the boots.
These are minor things which you could take care of,you will definitely improve with time,since this is your first model.
