Alright then here's some art that I can gauge, it may be a standard pose but it shows me that you think in "symbols"
Which means you think of the human body in your own interpretation rather than realistic sense. The Sub-Zero presented is a decent start and is far better than your other submissions but it means you can get better.
1.No line variation, consistent lines are unattractive and don't show depht
2.The muscle placement is wrong and just appears as quickly drawn in lines, this is an example of a "symbol" way of thinking. they aren't placed in a way that shows that these are real arms and how muscles stretch and contract.
3.His fingers are even worse, they seem not only broken but also mutated.
4.The coloring is sloppy
5.You don't seem to understand how cloth flows, it seems very thick on his body and doesn't seem natural.
You said this took hours so I'm assuming this was done by mouse, which is alright and I can gladly give you tips on how to color and do clean linework with a mouse by using Sai
