Pixel art. Vector. Raster.

Please learn the difference, then come back.

I know that what I made is a piece of crap, but is for that I decide to show to all you what i've done. For have critics, sure, but USEFULL CRITICS.
NOt just "Dot. Dot. Dot."
About the vector/raster thing, then I tell on this forum that I want to make PM-TTYD customs, Previous advised me to make it in vector grafics and later convert it in raster.
So please, can you clearly say to me what you dont like on my Morton, and if you can, a good way for convert vector in raster?
Or to make it in raster directly?
