Finally I can maker coments :D
Thanks for the feedback, i'm still learning a lot about this art.
I agree with the blue round thing... But i improve my tecniques... in this 2 months, theres a new Sprite of me in my profile if you want to see how much did i Improved.
And...

It's supossed to be reclining on a chair, but for that time I didn't know how to draw it jajaja 

Sorry if my English is bad... My native language is Spanish <3

Looks nice and clean, and the hands, though they are hard to do in very small resolutions, were done very well! By contrast, the shoes aren't as cool, as they are just sort of round blue things, and I think there is more room to express detail in the resolution and palette you have given yourself.

Also, in pixel art there is an idea to limit usage of color, and the handheld that this character is holding is made up of entirely different blue colors than the shoes, and I think the 3 colors you use for the handheld have better contrast and might look better than the 5 colors of blue you use in the shoes.

In any case, very very nice for a first 100% original pixel art! Is this man reclining on a chair or is he floating in mid-air???
