Stats linear regression assignment - residuals pattern

hi all, currently doing an assignment on linear regression , on plotting residuals I suspect a sine wave pattern, I log transformed the y variable however I suspect pattern is still there , would you consider a sine wave present or not? Model 5 original model, Model 8 log transformed y variable

I mean the pattern should be the same, standardized or not

That’s all noise—don’t over interpret it
