My first attempt at signatures

Disclaimer: I am not a design artist but for the sake of offering some feedback...

1.For a first attempt it is well done, certainly more than I am capable of doing with my limited knowledge of computer generated artwork.

2.The synergy of the text and image works well to convey a strong, clear, singular message.

3.You could improve on the composition proximity to achieve better unity as well as to demonstrate a little more creativity.

4.The geometric structure and spacing of the image and text tend to clash in an unappealing way, in my opinion. Though I do like how the text kind of reminds me of how the hair of an angry wolf might bristle.

5.I would try to find an image that takes greater advantage of the space

6.Try to set a "point of motion" so that your image and text can "work together". If you are going with an image of an animal, there is a lot of potential for taking advantage of using kinetic structure to portray a sense of time and motion with your sig

7.Red is the color of dominance in your sig but the size of the text contradicts what I think you are trying to achieve as the focal point in the text.

....just some thoughts. Good luck!
