these are sick, man. I'm a fan of anything vibrantly coloured, but your line work is just as good, imho. I love that you're applying the art to an actual cause based in reality. sometimes one person can make a difference. trust me on that one. it's just a matter of finding your cause, your outlet and your audience, and you seem to have found all three. by posting them here and showing your dedication you've already begun to make ripples that will be felt, if not acknowledged. hell, I've already devoted two minutes to writing this, so that's a ripple right there. though I wouldn't get cocky, because earlier I devoted like ten minutes to staring at a wall.
though I have to add, you're probably not gonna find anyone who disagrees with you on this particular site. you'd accomplish more by collecting a diverse audience. do you have a portfolio online somewhere? perhaps a deviantart account? a lot of artists from here are on deviantart too. sorry if you do and I've already seen it, I'm scatterbrained, and my memory is hit and miss
fly high, keep up the art..I'll be checking back to see the progress
