Tapas allows for longer file images though. WT allows up to 1280 height and Tapas is 4000 height. So you could combine panels into one image to allow less images to upload.
I agree with a lot of what people are saying here. I did notice the dialogue is a bit unnatural. It switches inner dialogue between the two characters which I personally think is strange, especially this early in the comic. May be better to focus just on one character's thoughts.
The "I'm freezing" line sounds awkward. I think if someone is suddenly being frozen, they wouldn't think "I'm freezing!" but maybe more "WTH?! It's ice cold!" or something like that. Fun fact about temperature when you touch something... cold and heat are registered in the same way, so if you touch something that is one or the other, you might mistake it for the other until your mind registers the actual temperature. I'm not sure if that applies here, but something to keep in mind maybe.
Art-wise, it looks amazing. I did notice in the first episode, the panel with the "An apprentice has been assigned to you", the perspective of the characters does look off, especially the guy on the right. You might want to reference some models for this because the angles are so unusual and you also need to take into account that the ground is at different levels for them, but their feet look about the same size.
It looks like it's a solid comic. I ended up not subbing to it though, not at all because it's bad but because it doesn't really interest me personally. I'm sorry.
