Overall, this looks pretty solid. The art is nice, with well-integrated 3D and photo elements. The main font is maybe a little fancier than it needs to be, but it doesn't feel too out of place in a comic, and it's clear and readable. There are a few errors in the English, mostly grammar, but they don't harm the readability of the story. The twist is quite funny and clever.
If I had to pick out one weakness... and we'll see if the judges agree with me on this, it's that pretty much the whole comic is the setup to a story rather than a story. There's not a lot of sequential panels showing your ability to tell a story with images; it's mostly a story told in text and illustrated with images. In comics competitions, I'd expect that to get marked down by judges... but it might be that since the story does lead up to the twist and it's nicely presented, it does well anyway in this case? Best of luck!
