I am already using 3D programs for help with anatomy, people keep mentioning but I am not sure what else to do there. Not sure what people are refereing to exactly. Is it the proportion of the character, their head/face. I haven't done shirtless yet so muscle can't be ;_; I am honestly a bit confuse on what to improve in that regard.
Now for the main curse, the review!
I like the start making it a nightmare sequence (a classic, but still works great) as it already foreshadows the dangers that will clearly hunt them. After that it slows down giving a good glimpse at school life a bit and nice use of intense moment causing flashbacks at first, but then they seem at any moment a flashback or visions can be seen. The story just started so there isn't that much to go with, but the fundamentals of it are being planted nicely and the story seem interesting.
You have really clean outline and great use of various thickness sizes making details stand out quite nicely. Love the colors, the stand out without being overpowering, specially the haze like look you give in flashback, dreams or vision. It makes it easy to follow what is going on during moments where present and visions intertwine together.
I would say the backgrounds perspective sometimes seem a bit weird and clash a bit with character or items. Is not often that it happens, but in some scene is noticeable (well in my case since I was analysis, I don't think most readers will notice as they don't stare at a panel for 10 minutes!). Outside of that nitpicking your art is great and it goes really well with the story!
I like your panel composition, I know you go for some claustrophobic moments sometimes and the panels help give that feeling. I do notice some chapter are longer than others and one could tell by seeing the 'page' count on the episode title, but for some it might seem they miss something when it goes from about 3 pages to suddenly one. Of course this part is hard to control but I think keeping it to one and letting the reader use to this style will work instead of the multi pages episode (mostly is to create consistency for readers expectations).
Overall you already had me before asking for my review (was sub for awhile) so I really liked your comic. Can't wait to see why she is getting those vision and what really haunts them.
