Hey there! Welcome. I'm new here too and haven't yet posted in the "new members" forum yet (waiting on some pics of my new boards). So it may presumptuous of me to be welcoming you on behalf of GH, but I'm going to anyway.

As a newcomer, I can say that for the most part, everyone here seems really friendly.
I studied experimental psychology at university also, with a particular emphasis on evolutionary psych and behavior analysis. What you are focusing on?
Also, if you do pixel art yourself, you should post some!
