Doodles and Finished Pieces

[Virt]

In the original artwork you referenced, it's not a full, poofy cloud. The poofiness is only on the outside, while the inside is like a concave thing where there's space for the eye to sit comfortably.
Also, in yours, the shape of the cloud's poofs just kind of disappear when they touch the eye, making it look like it's overlapping them. If you don't want to smooth out the center like in the official artwork, you could make the poofs closer to us overlap the eye, like what you did with the poofs around the spikes.
