Is there a statue of limations to appeal a sentencing once partial time is served and is released on parole?

In most states you have what's called an Appeal of Right, and an Appeal of Leave. An "Appeal of Right" is an appeal you file within a certain time period immediately following your sentence in which the appellate courts must hear and rule on the appeal. An Appeal of Leave is where you file a criminal appeal well after the statutory time limitations, it can even be a few years later depending on the circumstances, but the appellate court can hear the appeal at its own discretion, if at all. You may want to contact an appellate attorney in your area to see what your appellate rights are at this point.
