Good technique

The worst thing when you’re on your own, a self-taught person is that you have to improve your creativeness and technique simultaneously, and you need much time to make progress in your job.
When you’re going to an interview there is a question about your future, like "what you would like to be after 10 years". Recently I was thinking about the question, and I've got an answer. I’d like to have a great technique in representing my surrounding world.Because otherwise it's like you have an idea,but don't know how to say it.

There are 3 images that I've found at deviantart.com and understood that this is exactly what I need.
