SP= Self portrait I believe.
The shadows are all on the harsh side and they are not edited to my taste but they certainly make a statement. I would also work on the sharpness and DOF and pic a better background that is less distracting (as in the first one).
I could make critiques until the end of time but I am talking out of my ass. This is art and it is what you want it to be. Just because it is not technically perfect does not make it bad. Make the image look how you want it to look. Self portraits to me are about showing yourself and in these I get a sense of who you are and by this definition, they are alright.
