I've been commercial artist for over 30 years, and I can say with total honesty that you have more talent than most of the people I've worked with. I agree with Zathros, you should put your work together in an art book and look to have it published. It would really appeal to dinosaur and art fans as well. You have a natural gift for illustration, and a love for your subject matter that clearly comes through to the viewer. Superb artwork!
