uh i can help with his explaination

for one the neck of this guy is very thick.
if u were trying to go for a buff guy look u made the legs quite small.
and there is the arms, they look awkward, there to straight. u should put some joints in his arms. but his right arm is especially weird. the arm looks like its been twisted, and he is holding the weapon in a weird way.
the weapons handles should also be thicker, such a guy wouldnt be able to hold on to that thing with handles so small.
the head is also quite large and u have misplaced the eyes. they look crooked.
it also doesnt make much sense how hes covered in blood but theres not a single dead body around.
and it would be cooler if u added more detail to the pillars.
u should also shade a little bit more.

but dont worry. skills come in time, and hard work.
and u still have alot to learn
