Hey! Thanks for the compliment. I love Illustrator because it grants me complete control whereas Photoshop can be a little more unforgiving. If I have a complete plan as to what I'm going to draw, like with the monster drawings I did, I will work in Photoshop because I have a full range of coloring/shading options and can just build the image overtop of my sketch. But with something like this image, where the idea was there but the final look was a bit up in the air, I worked in Illustrator because I knew I would want to move things around and resize. Plus I wanted things to look crisp and brightly colored with fun highlights, which I'm much better at in Illustrator. Hope that helps!
