Comment I shall because oh my goodness this is beautiful and sweet. It's very often I see these two at Waterfall unless it's another person drawing them dancing. So this is nice to see, especially with it being a mini family moment with the romance low key. I really love how you've done the water, it's gorgeous and suits Waterfall, and goes quite nicely with Toriel's and Sans' color patterns since they're all part of the "cool" color wheel. My only nitpick would be Sans' arm over his leg. It doesn't seem propped up on it, more like hanging over it. (Then again would be tricky to do clothing folds with how skeleton bones are so I'll ignore it.)
