Vision: It's a pretty good looking drawing. THe only reason why I didn't put 5 stars is because when I first looked at the drawing, I thought it would be an animation because of the almost blank space left at the right. (Not that I'm disapointed it's not an animation, it's just that I find the space on the right too blank. You should have added something in it.)
Originality: I really like the title. Pretty character/drawing fitting. I like the fact that after wubbing like a boss, Vinyl will be nomming like a boss. Maybe you could have added something like a vinyl drawn with jam on the toast, but overall, I find it pretty good in terms of originality.
Technique: Pretty good overall. Nice looking wood texture, perspective is good, colors are nice too. But, once again, I find the right part of the drawing too blank. You should have added a window at the right of the wall behind Scratch. And if you have some troubles drawing background, you could have just colored the window with a blue-ish color and added some reflectoins (Like on Scratch's shades)
Impact: Well, it's a really cute drawing. I can picture perfectly Scratch have some meal right after making some good mixes, and Octavia thinking in the other room "Okay...I've got 5 minutes to find some ear plugs".
Overall: Pretty nice drawing. Also, this is my critique, and these are your drawing. You do whatever you want with your drawing and you think whatever you want of my critique. But since you asked for a critique, I thought I could go for it Anyway. you did a pretty good job on this drawing, and except two-three points that disturbs me a little, I love it.
