The render blends too well with the back ground. Other than that, for a pop-out sig, its pretty decent. Its a little basic looking but I like it. Good job!
Looks good. Only problem is the render isn't of great quality and the edges are al ittle hard. But it looks ok though.
After you've deleted the background, save it as a PNG so that it will save it with the transparent background. EDIT: NVM, thats my schools internet being lameass. EDIT 2: even though its popout, dont use it cuz its too large
