A very good start. I really like the background with the fire, and nice job if you cut that render yourself, but is was really low quality to start with. The first thing I noticed was the sigs dimensions. Very awkard

. I prefer to use something like 100x300 or 110x320 (the hieght is normally close to one third the width of the sig). There is also too much text. Normally people try to put as little text onto a sig as possible because it is the hardest thing to get right.
Nice start, it always fun to see the kindle of the fires of the great sig makers of tomorrow (LAME LAWL). I'm no pr0, but feel free to take my advice
Peace out,
Doctor
