Nice work on the candle details, you really seemed to get the melty/goopy effect to show!
Anatomy and facial details seem pretty good as well as the clothing shading.
The only real thing I can point out that could be tweaked slightly would be Lorne's left leg.
His left thigh is just a little bit thinner than his right thigh...but then again, I don't know what illness he has. For all I know he has degenerating muscles in his leg, in which case it makes sense. :P
Other than that I don't see anything else wrong with this drawing, good work!
