It could use alot of improvement, like your lighting placement is good but makes the whole sig look sorta faded; try toning it down a bit, and maybe make it a bit darker and realling defining the depth because I can really see this one being really good. If you have time make a V2 and post it
Maybe make the text smaller and try hiding it a bit too.
looks nice leeann...the text though needs to b lighter lke dan told yah...maby add a lil bit of colors (lighter) that are around the text so u can c it better or make it a dif color text but i love it nice job!
