Thought I'd try a critique for your group. I'm basing my critique on dA's Help page concerning critiques, and do hope your find the critique acceptable.
I enjoyed the opening paragraph and had to continue reading. I rate you high on vision and impact for that reason, as I am easily distracted. To give you 4.5 for technique seems harsh to me, and I wish there was a way to go from 100 to 98 or something similar, but I marked it this way because it is in the opening paragraph that I noticed, "Deny my" instead of "Deny me" or possibly, "Deny my demands and..." and a few other things. I belong to a group that meet at our library that don't allow critiques for proofing errors, we are to critique content only and not proofread, which is more fun, but I thought I'd give input on that count.
Trouble is, I don't know if grammar rules are different for other English speaking countries--we have spelling differences, such as gaol or jail, or colours and colors, defense and defence, etc....so I won't point out spelling or any other technique/proofreading errors for that reason.
Back to content: wondrous! I felt sorry for Jeremy when I realized he was in pain, but upset, too, that he would choose not to enjoy the time he had. That changed to hopeful when he started changing, but, alas, Jeremy was meant to meet his end no matter what his form, it seems.
I wish the transition from Jeremy seeing the light to actually meeting the flames had gone on longer, the magical moth trying to reason with him, even as he tried to reason with himself further. Get to know more of the magical moth's intentions, a reason behind the magic. However, because of my interest, my want to know more, I say the work is that good, because my interest was that captured.
Ah, what a tragic end. The moth may want to consider morphing his next subject during the day, unless it is a magic that only works by lunar power...
