Would you mind elaborating “remaster” for me?

Ummm… I would say art is very subjective and this is looking like a finished piece to me. To make it “better” would require you to say what you think is lacking and what would make it better like, do you want to see more lights in it, more shadow, are you looking to make it into a banner, a signature, do you want colour changes? Etc.

There are tons of things we artists can do with the image, but honestly it’s a really vague request and won’t get you far unless you explain a little further mate!
