Nicely done - if it was a request, then you had to do it the way they wanted it. The model is quite popular, I see on Pinterest.
Myself, I cannot paint on request - so I turn down commissions because of it. I either feel like it, or I don't. Most times I don't, because I am backlogged with so many of my own projects.
Good luck to you if you can get commissions and be able to do it. You do have some good painting skills.
