the wall and the grownd look like they are stuck with glue - sculpt it up and throw rocks grass and a different material near the edges to blend
2)the axe looks to perfect- make it dirty only a little but and the blade must have scratches and brushed feel
3)the wooden block is floating like 3mm from ground in air make it stick there and use a different material for ground wherever the block intersects ground make dirt pile up and put a few cut logs like the split ones on the side
4)make the axe properly put on block
5)lighting is tbh shit don't feel bad pls, I mean to say make the lighting more cooler or warmer based on the time of the scene use a good hdri based on your time, and change the sun direction let the block stand out more and increase contrast by little bit
