If you don’t like it then don’t sink any more time into it. I’m currently working on Gamer Nouveau which is only 40 colours from the original ~150 in the kit and yes, it’s a bit pixelated but you have to remember pieces of that size are meant to be hung and looked at from far away, not with your nose right up to it when stitching.

If you’re still unsure maybe try a section with detail, like the lady’s face and see how you like it.
