I've had two that I felt were over my head, a Fujimi Enthusiast kit, and a Trumpeter Pontiac. I'm not a great modeller, but with time, patience, and care I was able to finish both. It kinda changes your mindset, I have to settle in for a long project, rather than cranking out an AMT or Revell kit. I've built a couple of Tamiya kits, and while they may look intimidating, they go together well, in a sensible way. I say go for it, I think you'll find you do have the skills, and you will enjoy the process.
