When it comes to painting a black crow in watercolor, there are a few things you need to keep in mind. First, you need to make sure you have a dark enough pigment to get a true black. Second, you need to be careful not to overwork the paint, as this can cause the crow to look muddy. And finally, you need to be patient and allow the paint to dry completely between layers.
With those things in mind, let's get started!
To start, mix up a small amount of black paint. You can always add more if you need it, but it's better to start with less than to have to try and lighten up a too-dark paint job. Once you have your black paint, load up your brush and start painting in the general shape of the crow.
As you work, keep in mind that crows are not perfectly black all over. They have some lighter feathers near their belly and face, so don't be afraid to leave some white space as you paint. Once you have the basic shape of the crow blocked in, start working on the details.
Paint the beak first, using a small, pointed brush. Then add in the eyes, painting the irises a dark black or brown. Finally, paint the feathers, using long, sweeping brushstrokes.
Remember to take your time and be patient! Watercolors can be unforgiving, but with a little practice you'll be painting crows that look just like the real thing.
