So I've decided to redesign Thetas' stripes to make them undulate more like tiger stripes. I've only done the back because a) I'm a little pressed for time and 2) the front reference doesn't change in any major way.

Unfortunately I've lost the un-striped reference I created so had to paint over the stripes in the old reference and then put the stripes back in. You can see some effects from the painting process that detract from the image. But this was never intended to be a great work of art so they're going to stay, as I really don't have the talent or motivation to remove them.

Also, due to the lack of talent, some of the stripes aren't that good. Mainly the stripes on his right arm, and the central back stripe is too thin around his neck. So I want to make it clear that this should only be used to give the general outline of his stripe design and does not need to be copied exactly when used.
