Can my teeth be aligned correctly? Missing upper left lateral incisor. (photo)

Had my top left lateral incisor exactred as a kid. Got braces 11 months ago, my ortho extracted my bottom left first pre-molar. I have been wearing braces almost 2 year and still not happy with my teeth. Left side seems smaller, right side is more arched. My front teeth seem slanted to the left, left front tooth seems higher in the gum. Right front tooth is lower. How can this be corrected? Do I need to extract another tooth on my right side, top & bottom? Before n now pics included.
