Watercolor Digital Kids Room Art for us to print later

I'm looking for a beautiful watercolor digital canvas print to gift. I want the exactly the same sketch as to what I will be providing.

since we’re doing digital will I have some flexibility on what size I print it to after you provide them? I understand you’ll want an estimate on canvas size to get the details right when they go to print, but I want to understand if I do change my mind on canvas size later on… how will that impact your work


Please provide examples of previous work.
