LOL I could imagine you persuading your dad right now...
And wow. You're so good on paint. I can only make sloppy happy faces.
The only thing annoying me is how straight the posture is, like a ruler. And the ear seems like it's cut off literally.
Otherwise, everything is perfect. Your color theory is correct by putting together warm colors. Also the detail of Axel's hair is amazing. OMG Axel...
And don't copy someone else's style. It's ok to gain experience from them, like I used to do reference pictures from looking at manga. But then I evolved my drawing to my own style.
So yeah. If your dad's there, tell him you're going to be an excellent artist in the future and you need the tools to be one.
