Oh my this work made me laugh so much. I enjoyed it all, but I'll give you a simple summery
Vision: Very simple yet detailed. They all seem to be drawn with a large amount of time.
Originality: This work is rather original. Now I mustache you question... what do you think? This is great
Technique: I enjoy the lines softness as they dont over power the drawing yet make the image stand out. If I could suggest, some shading would be good here and there, but great over all!
Impact: This made my day as I couldn't help but laugh. The expressions on their faces to the style of mustache. Amazing!
Overall, this work was great and I hope you critique my work in the future. Thank you for reading
