Big things I immediately notice, their faces they are strange they don’t look right at all, the eyes are to small the noses are to flat the mouths are just off…
Extend the background and their legs down if this is for your own personal use, give yourself 2 complete characters to work with at a later date in case your friend decides to make book 2.
Normal I would pick at your composition but I understand this is supposed to be focusing on the characters so it is alright.
Their positions are a little bland think of how you can make their silhouettes more interesting.
The character on the right first-
The hair is not man hair, I thought that was a woman when I first saw it, paired with the earrings and the weird tattoos I was very confused the first time I saw it.
His costume seems strange too for some weird futuristic apocalypse as seen behind them a shamanic looking white guy does not fit in.
On that note the magic is interesting but doesn’t work for me it feels like a completely different style. It looks good but belongs on a different character
I am really not digging the chest tattoos
The one on the left-
Better than the one on the right but still some issues
I feel like this one fits the genre better except for the weird sickle. It is an extremely unwieldy item and for her body size she would not be able to hold it with such easy, secondly she is holding it wrong. Sickles have their edge on the inside because they are used for cutting crops, so unless its some awkwardly customized blade she isn’t killing any corn holding it like that.
If it is customized then it doesn’t have a hand guard and the first time she runs that into someone and blood gets on the handle and her hands slip up uh-oh there go all of her fingers. Also if that is the case, the witch doctor is about to slice open his back.
What is going on with the coat, the bottom is pulling weird and how is it staying closed while she is what I assume running. The hair is interesting but try getting it going all in the same direction if she is running and not flying everywhere.
Hope this helps
