I agree. Her face looks weird, the lipstick looks awful, and her back looks like she's in huge pain from that arch she has. Hell, her right eye is looking straight while her left eye is looking up. All that just for a spanking scene would be a slap in the face.
I'd much rather focus on scenes be more actual sexual stuff than something like this that's tangentially sexual. Focus on the main things first, boob job, blowjob, fucking, etc. Spanking ain't it.
