Digital is fine actually, as long as you follow the same steps in this tutorial and draw it freehand :D
Avoid using premade shapes or any tools like circle brushes. ^^
I explained the circle exercise in the beginning of the post here, which you can do digitally too.
Looking forward to your work :D

I finally made one and here's the link A step by step progress is showed there and thank you for the challenge ^^

Nice! You did an amazing job! :D
Also makes me very happy that the tutorial works ^-^

If you have the bird on a separate layer, you can make the area under the bird lighter (or white), making it stand out much more from the background ^^

I didn't know I could do lighten some parts of the image that way. Noted. I'm learning :)
