The rules for redrawing the Tyger are simple:

If you are drawing on paper:

Use a standard A4 sheet of paper or a framed area that is roughly 4 x 2 (w x h) in dimension

Feel free to draw in black & white, in colour, with pen or paints

If you are drawing on a computer:

It must be in the .jpg file format

It must be 376w x 171h pixels

It must be an image of a Tyger!
