This is absolutely stellar work. I'm not as well versed in graphic design as I would like to be as I've only just begun to take it out of the amateur realm and move into a semi-professional level, but I believe everything you've posted here speaks for itself. You've got a real mastery over the principles, and the balance and emphasis placed in the bottom two pieces has me completely taken aback. The color, the composition. They're immaculate. It's silly, but even your avatar speaks to me. Type can be so, so much more aesthetically pleasing then its given credit for.
Your portfolio, though I've only gone through a couple of pages so far, has already completely blown me away. You're no mere graphic design hobbyist, this is professional and concrete. A quality of life can be built on this work. I can promise I will be following your entries for some time to come. You've made a sincere fan out of me. Thank you.
