Very nice complimentary colors/contrast and composition. You've got a great eye for that. Focus seems to be a hair off again & a bit of noise (I'm not a big fan of noise personally - some people like it). Otherwise, beautiful job.
That yellow really does pop out at me and that is good. I think it would look better if you used the rule of thirds but either way it is a great start to a portfolio. Great image thanks for sharing.
