Okay, here's some feedback like you wanted. Hope nothing comes off as harsh.
Page 1: The colors go really well together. I like that you have a closeup of the character and an establishing shot of the background.
Page 2: The font is a little hard to read. I'm not sure what crusts are, but maybe that will be explained later. Great job with expressions.
Page 3: I like that you are showing the overall environment.
Page 4: I'm not sure who is talking. Your vertical gutters are different thickness depending on the page, maybe try to make them a standard width.
Page 5: The sound effect is a little hard to see in panel 2.
I didn't realize the main character was a kid at first, so I was a bit confused when I got to the later pages. (I read the description quickly, so I missed the "young" lizard part.)
I'm not really into swearing or violence, but overall, you're really skilled at story telling and drawing. You have good pacing, cool character designs, a good balance of closeups and zoomed out shots.
All the best to you!
