Hello John!
Don't worry, this background is great! I love the texture on the wall. The door handle looks very real. And, the face looks very good.
Just a little suggestion... I think your model would probably look better situated a bit higher towards the top of the canvas. In both Margaret Carter Baumgaertner and Tom Browning's workshops the models are usually 2-3 inches from the top. I have tried lower and higher and tend to agree with them. I hope you don't mind but I cropped your painting to show you what I mean.
Also, It might be the digital image but her hair color seems very close to the skin color creating that surrealistic effect again!
