Is it possible to do the ink layer last instead of first if you're worried about accidentally washing it out? Sorry if it's a stupid question, I'm pretty much exclusively a digital artist! XD
It may have looked a bit nicer if you fadedout the edges, but there is definitely nothing too wrong with it as it is :)
I answer such question all the time:) And the answer is no. There are two types of ink - water soluble and water resistant. You can take the second one to the bath if you wish without spoiling it:)
