Not bad hun, the first thing you need to do is get rid of that white border, it doesn't fit well with the signature, if you want a border try to make it blend in with the colors of your signature, or maybe just a simple black border. I think it would look better if you darkened the whole signature a little, its too bright on the right side and looks a little out of place. I like the color choice though and the effects within the signature. Keep it up and good job.
Hmm.... I think you need to work on getting depth in your pieces by way of color. Try to give your sigs a more saturated feel. Use darker colors for gradient maps. That kind of stuff. Also, Try not to put too much in front of your renders. Try to utilize the lighting already on the render instead of trying to pull a light gradient over it to give it lighting. That will help a lot. Keep up the good work.
