What do you do? You channel your talents into something not forbidden by Allah. Allah has allowed you to draw anything at all, just as long as it's not an animal or person. The world is your oyster. Think of this as a good thing, actually. You're going to be coming out of your comfort zone, be forced to draw things you're not used to drawing. It will take more effort, but you may discover you're good at things you never even knew existed, whether it's surreal art, landscapes, abstract, impressionism, etc. Do a bit of art history research and try to find what you like most, what you'd be best at. Find your niche'.
I'd always loved art, and growing up, I tried virtually every single form of it possible. Pottery, sculpting sketching, calligraphy, cartooning, working with watercolors, oil, chalk pastels- you name it, I tried it. Sketching was always my favorite, and I wasn't too bad at it either. But then I realized that drawing living souls was prohibited. I stopped, and began searching for something else. I found photography, which I love a million times more than I ever did sketching; I'm better at it too.
So basically, use this to your advantage, and don't give up on art altogether.
Whoever leaves something for the sake of Allah, Allah will replace it with something better.
