1. I had a little trouble with this one cause I wasn't quite sure what you were going for but I tried to nail it!
2. The purple hue on the base color you chose wasn't very pleasing, so I went with a bolder rusty red.
3. I made the eyes a duller green so they matched better with the design
4. Try to spread out your stripes a bit, make them flow over the body of the dog. I see you tried to wave and curve them a bit but it looks more like squiggles. try looking at a tigers or zebras stripes. They come to a point at the end of the stripe. try using an eraser tool to sharpen the ends of your stripes.
5. I also added some rusty red dots throughout the body as well to bring it all together. If it were just the stripes on the eye and front leg it would look a little out of place with the rest of the body. You really have to tie it all together!
