Man, go beg your sis to make more fanart cause this is absolutely awesome and I find it intriguing that everything on the drawing is from the game, the clam, the light, the jelly, the coral, the leaves, the helmet and the health plants. Totally awesome man and of course sis of man.
If she draws more again, ask her to make fanart of the bosses with Naija, just like the picture of Nautilus Prime and Naija hiding.
