Hi bro nice graphics there ^^, *pinoy here also*
I've read on your your thread about having trouble with someone just for a quote, I've also had problems in the past regarding this matter, I've had a hard time promoting myself as a freelance graphics artist too, so what I did was, *I was on a freelance site before, so I searched what the market demanded* then I made mock up designs * cause I've no clients also,*, made designs that where appealing to the market, started from there, then when I was hired, gave professional work, not only on graphics, but most importantly on communication. then rest was history, I'm not saying that you were wrong on asking someone to hire you just for a portfolio, cause it might make them think you are desperate and unprofessional, just enjoy what you do, and rest will come,
and now I get to choose which job offer interests me and which jobs I'd like to take on, cause I already have my own reputation when it comes to services and professionalism, *haha if I see an offer as boring, i'd ignore it~
trust me , the best part is when you get to choose the job,clients you like , and not the job you just wanna turn into your portfolio~
goodluck~
