Idk, my ports are getting a LITTLE more popular (lol) and I was thinking about adding a symbol or something to show that it was made by me?

I wanted it to be relevant to either Momma or Submerse, but DA name is probs the better choice because that's where I post art.

Anyway, submerse is sinking into water, so obviously i chose something watery to represent that:.... a teardrop? kind of anyway. the inside is kind of like a flower pattern. see: [link]

ANYWAY, I WAS WONDERING if:
1. should I even use a signiture
2. is that a good symbol
3. is the symbol too bulky
