Are these sprites and what are your fav?

[fighter662]

Do you think these sprites are good(made them in paint)(2 from photofiltre)
and what are your fav? fell free to say w/e u want. I need the criticism to create better sprites.

thanks. All i did was use one main color, made 2 darkened colors, and pretended the sun was behind the char. Anyway the buff was my first shirtless guy. lol.

I almost forgot. if i were to start a char which one should i do (besides the 2nd and 3rd one).
