I have to agree with zero-point. The illustration of Petrie is very well done, though unfortunately its juxtaposition with the background makes Petrie look a little flat. But this doesn't change the fact that this is a nicely done drawing.
Thanks, bud. And yeah, I do tend to struggle with juxtaposition. There's one thing I can say, though: I tried taking your advice on not making the character outlines so obvious like I had done on my previous DuckyxPetrie pic, so that it looked a little more smoother. Other than that, let's just say I'm a little lazy with shading effects.
BTW, what program do you use for artwork? Seeing that Paint.Net is obviously not the most effective but it's what I'm stuck with for the moment.
