, Sorry For A double post but haha. I used a stock and a render and just a duplicate and gradient overlay and got this ^-^
^ I think that is by far your best one xD Read some tutorials and try to apply some of the techniques shown on them to your own tags :] Its a great way of learning some new techniques that will really boost your tags up Keep it up :]
Number 1 thing work on the text and the blending and the backgrounds. but welcome to graphics all about trial and error.
Ok. Im not that good at these I have been working with signatures for about 1 month or so, so they are not the best. :]
I would read up on some tuts and learn more. Seems you got the basics down now try for more complicated things such as adding clipping masks and what not.
