Nice topic Tas ... would give this a go however I will be off on holiday for two weeks when this challenge ends (somewhere hot), so not sure if I would be able to squeeze this one in before I go [:'(]
Looking through there is some really nice work going on here ...
Quidam - nice idea and good use of a doodle
edart - really nice piece of work
solomon01 - like the craft and fire effects, looking forward to seeing more of the dragon
tector - smoking lady, nice take on the concept
martin - agree with tector ... think it is something with the lean of the buildings between left/right sides is a bit out from what I can make out
dragon - you've got a really hot babe here 
bubble - nice experimentation with ideas here
rainforestgoddess - love the flame effects and the planet looks hot however fell a little bit of softening in places may be needed?
xjustanotherstarx - lovely cloud effects although think some could do with a bit of edge softening and highlights in places to add just a little realism?
Darn you have all got me fired up ... where's my sketch pad?
