Kirara on GrandPa's car

Here a sketch showing Kirara (Kilala) relaxing on the hood of GrandPa's (Kagome and Souta's grandfather) car and he tell Sango then Kirara shouldn't relax on the hood of his car. Sango, Kagome, Inuyasha and Miroku do some speechless faces. Note then it's the first time I sketched GrandPa and Kirara. ^^;

And the car in question is the intermediate mid-size Oldsmobile Cutlass from the "Colonnade" generation (1973-77)
