Digital drawing - Penguin
Digital drawing - penguin
If you are going to draw digitally, you can work from a reference photo. Of course, you can use it as a background and 'trace' the lines, you can also put the photo next to your work field and draw it back.

Meet the penguin! I really like to do this, though! The net unrealistic/just cartoon drawing a picture.
In Sketchbook pro a lot of practice to discover all (far from all) options.
Which animal would you like if I sign it?
I don't know if it's done once, but a cow, or a lion or maybe a bunny. Or maybe even a penguin 😉
