Honestly, SEO, you kind of brought it on yourself. He was going out of his way to be kind and only really focused on two things that bugged him, two things that he felt should be known and addressed so that - even if you didn't want to address in that picture - you could press on in the future with the added perspective. That's how constructive criticism works, and you did say you asked for it. Honestly, if he wanted to be as nitpicky as you're making him out to be he would have addressed a lot other things, like the weird head proportions, occasionally confused perspective, weird coloring and a few other things. But he didn't. I can't fathom how you can see his post as negatively as you do.
What kind of behavior is it to get mad or annoyed with someone who bothers to put in his time to comment on your work? Yes, he critiqued it, but he also praised it as well. To be blunt, you were acting like kind of a child; and yes, perhaps Cshad shouldn't have pursued the matter so vehemently, but that doesn't excuse your initial behavior, either.
I'll be honest and say I didn't really like your pikachu picture (I find it a little baffling honestly, the lugia one in the first post and a few others are much better). Just keep in mind that CShad did; don't just focus on the negatives, and don't over-react to critique as if it is some kind of horrible nitpick. It's not, and it doesn't change the fact that he had good things to say as well.
That's all I really wanted to say. Not trying to pressure you into anything or attack you or anything like that, there are just some things I really felt needed to be said. And unless you really, really give me a reason too, I probably won't press the matter any further.
