Actually, the missing outlines on bottom of sprites' feet and shoes is often done; usually to make the character feel more grounded, I think.

Wondering why he is so hunched over/half-squatting.

What are you trying to achieve with this idle animation?

I see her sword literally dripping blood, but no wound on the werewolf.

I often lose motivation at the time when I post on forums like this one for help. It's because I'm stuck.

Getting stuck is no fun for anyone, but getting past it and learning something new can be.

I'm not sure about your actual artistic abilities in general, but I know at least for me, that I have little-to-none outside of pixel art tech and this is why I hit a wall often in my pieces. I plan on studying to really improve as an artist in general, and hopefully this will keep me from hitting these walls so often, and improve my ability to render more things. I think with more knowledge and experience you will have more ease drawing things, and thus more fun as well.

My advice is if you're stuck on something for too long, move on. Don't force yourself to have a miserable time drawing something. (Although sometimes it helps to draw outside your comfort zone to learn new things.)

You need to just keep on trying new things, don't wait for inspiration to hit you in the face, because sometimes it won't.

Often I'll draw something and completely hate how it's looking and scrap it. Every now and then, though, I'll make something I'm actually very satisfied with and it becomes a joy to work on. (Because when you have a great start, it's hard to make things too much worse no matter what you do, really.) Those are the pieces you should probably see through to completion and really seek out help on if you get stuck.


Hope this helps, and good luck finding some motivation. 

Btw Pixelation is probably one of the worst places you could go if you just want recognition on your work.
