This is literally Mettaton in the ending where they became king of Underground.

One nitpick: The cake looks like it says "MII" instead of "MTT". That's a little nitpick, though. Otherwise, awesome job! Everything is shaded very well, right down to the sparkly wrapping paper and foil balloons! All the little touches make it amazing - the stars on the table, the heart on the cake, the pink fire on the candle, all of that! Really well done!

Looking at this picture and the other Mettaton you drew, I would love to see how you would draw 1010, the robot boy band from "No Straight Roads". I feel like the stylistic choices you made in both of those artworks would work really well with 1010!

Darling, I can show you where my love hides ~

(happy b-day)

Looks good.

i love this!!!!
