Since apparently you wont take anything to actually improve your art, but simply your pose, ill crit on that.
your front view portrays to me two things:
spread legs, and wide shoulders.
well...two things that stand out the most.
ahem
your sideview person, while I understand it is sideview and will look thinner, doesnt portray these things to me.
it looks like a completely different person/pose.
IF you really intend to keep the pose of the front view person(though i dont think that wise, but you are not asking for crit on it)
then i think you need to make the shoulders and legs in the sideview match those of the shoulders and legs in the front view more.
the arms also seem smaller.
even though they are different views, they are still the same amount of mass : P
hope this helped.
