My first few attempts at OotS style imagery...

[Evil_Pacifist]

Here they be! Any criticism is helpful, I won't go emo if you don't like 'em.

In the order that I made them...

I bet you can make the eyes more oval-y and bigger. The arms on the third one are too short. The heads are a little too small on all of them. They should be about 1/3 on the total height.

i like your chainsaw

the weapons are very cool, the sword and the axes.

The legs from the second one is too large and the arms of the last it's a little short indeed.

It looks like you're using Paint Program. There's noting wrong with that, but the lines ome out a little bit blocky. Other than that, eyes are usually more ovals, and the faces could use a little mroe exression, wither with eyebrows of something. Overlooking thoes, they're good!

The Unibrow should almost always be present. The heads should be larger about 1/3 the height and the body should be about
2/3 the width of the head. The Legs are too long on both the first and second one and the arms are to short on the last one the body's of male characters should always be a perfect rectangle and the armor/clothing will shape it out.

The eyes should be large ovals usually one being very slightly smaller. And any outside shape(the edges) should have the thick black outline for instance the armor on your third one would be outlined in black or else it kind of looks like a floating shape.

Ok I am done. Have fun. I am not to good at it either but I enjoy doing it I haven't made a new one in like 6 months.
