You have to decide whether you want to stick with liking the way it looks with your title as, which is not likely how buyers will search... or title and tag your art the way you think a buyer might search and save the name of the piece at the end, and include it again in the description.
We've all had to make choices to be relevant to our buyers, if we want to sell our products... and I don't consider it selling out, because if done properly it will increase your views, hearts and sales... and that's what we're here for ;)
BTW, cramming your titles with keywords isn't necessarily the way to relevancy here or with google... for one thing, their cut off is about 70 characters... plus it could have just the opposite effect, because they may penalize keyword stuffing.
Titles should identify the item at the beginning with relevant keywords and phrases, then embellish a bit if you must with a bit more info and/or add your creative name. Use those same keywords and phrases again in your tags and of course repeat them in your description, but try to make it as readable and as grammatically correct as possible for the sake of your buyers and google.
