Need help identifying this painting

Hello everyone. My name is Cody. I have a canvas painting that I am trying to figure out who painted it and how much it might be worth. Just a little background info on what I know about it, which happens to be very little haha. This piece of beautiful art, In my opinion anyways, has been in the family of a close friend of mine for around 20 years or more, that's what I was told atleast. To be honest that's pretty much all I know. So instead of spending hours on end looking for similar paintings and trying to figure out the signature on the front or the marking on the back, which is 3.T-1063, I decided to create an account on this forum looking for help. Here are some pictures I have. I hope someone can help me out, thank you everyone.
