Nice stuff as always man, but be careful with the shadows in panels 1 and 4. The way the shadow is cast makes it look like the characters are right up against the wall with a strong light source coming from where the reader is. Then in panel 4 you have a hard shadow behind the guy as well, so those 2 panels together bale it seem like he is sitting in the corner with 2 very strong light sources.
Hope that makes sense...
