Looks good except one moment. You don't have much consistency between objects and evn incline. The left chest on the preview is aligned with walls so it looks normally but right chest is weird. As you didn't add incline to luke, character and column (I am not sure about the slime but looks good even with this small incline) I recommend you not to add incline to the chest.
And in general the chest have another perspective. Its Z coordinate points to viewer but other sprites have z coordinate point to up of the screen with some small angle... I like it except chest
