Awesome, you're work continues to amaze me. If you don't mind me asking, how long have you been building models and how long did it take you to get the the level of craftmanship you are at now? Been threatening to get back into modelling again one of these days, models are in the cabinet just waiting to be built, but I am the type that seems to need to research everything too much and thus just never get started on this type of stuff.
Keep up the execellent work, and I'm looking forward to the tutorial that was eluded to earlier.
