Hi Fortunastreet,
I think that it's also perfectly valid if you want to keep the artwork as it is for your own personal reasons. I should preface that it was just something I, a random stranger, had a random opinion about XD;; At the end of the day most of us are just doing this for our own fun and you should do what you feel is best. If it sounds like a fun challenge to recreate the image yourself and see where you can polish it a bit more, then you should! But if it seems like tedious/annoying/frustrating/expensive, then maybe not.
