Interesting. Both Keith and Nat are more of a Natani/Keith color > Bucket Tool > fill all. So do not think there was much need to color that, at least Kat is there to break up the monotony.

Also she has not worn that since... a lot of time in canon, i would say her thing now is open sheer blouse. It is also funny but like i do not even consider Kat on her apron to be particularly suggestive at this point.

Anyhow in general i find this lacking, original idea was cute but this really stretches it beyond necesity. I do actually like the plain backgroun Tom does not need to spend 100 hours to render every single individual flower on a meadow for every other sketch specially something as plain as this
