Okay lets start this with the greatest problem
Obviously drawn without reference
While drawing accurate poses without reference is an important thing to learn, drawing without reference when you this early on the learning process is a terrible way to learn. If you had for example goggled the words âSWATâ âhunter rifleâ or âhunter shotgunâ youâll have been greeted by lots of photos of people holding guns in hundred of different ways and angles. And donât be afraid of âcopyingâ everyone does it and it is literally the only way to progress.
Most of your errors could have been avoided if you had done that but I assume you did that while you didnât had access to a computer but now you know for the next time
Anatomy
Well I ll be honest the basic anatomy is well kinda messed up, Ill post my kinda more acurateish skeleton example down below (by the way you should draw this skeletons to establish the pose before starting, they make everything easier) which also ejemplifies the biggest problems with your drawing
-Note how the lines that define the torso follow the line of action
-Notice that if you draw a straight line from the head to the floor it fall roughly in the middle between the two feet
-Notice how the imaginary line between the knees follows roughly the same arc as the hip line (objects like pouches in the upper legs should also follow it).
-Notice the more natural arc of the arms
-Notice how the gasmask i drew has the far filter bigger than the near one thatâs an error from my part donât draw them like that
-Also dont be afraid of using more curves in your drawing, no one has the the shoulders that rigid for example
That is basically it, also congrats on the hands they look well.
My advice is: go to the deviantart forums (or even better conceptart.org) and ask for help on how to get better at drawing, someone way much better than me will definitively drop by and help you/direct you on the right direction.
What I can tell you is that If I were you Ill practice drawing basic 3d objects also, it may be extremely boring but it helps a lot when it comes to adding the muscles and clothes and pooches.
