i like what you are doing here. i suggest maybe making the enemies a bit more detailed. not in the shading and color use, but in the elements of the monsters. the simple aesthetic works, but i think they might be a bit too simple..
thank you for the suggestion, ill work on that and maybe keep the original designs of the enemies as well... but thank you for the suggestion and for your time on telling me how i can improve the pack to be the best i could possibly make it
