OH how we have all been there. ( Stubbing our toe and making a big deal)
I like the way you drew them, and love how chell's reaction to it seems more like she is getting slowly ripped apart rather then she hit her toe. The shading is marvolous, and the tones and colors add special effect, and I can see you took your time with each panel.
I also like the exspression of wheatley, and it looks like he is thinking " Is she bleeding?!"
I enjoyed reading this and hope to read more your your wonderful comics very very soon.
