Nice work. Like Lews, I'm no pro at this sort of thing (I actually haven't even read a real noir comic before) but from what I've collected from other noir style things, your aim seems well on. <img src="/ubbthreads/images/graemlins/delight.gif" alt="" />
Keep at it, and I know from experiance that with anything (drawing, writing, etc.), the more you go at it, the more your style evolves and improves. Especially the more you expose it to others.
Hope to see some cool stuff from you in the future. <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
