Its nottt thattt bad. But the graphics COULD be better. But I cant really say anything about graphics myself... And also the arms, well gloves are choppy.
also if there is lack of an outline you could always create it as well. it's essentially just black so use a solid black brush to "create" more outline.
If you're using photoshop when you first cut out the render from the background CTRL+left click the render to reselect, then go to select>modify>contract>1 then select inverse> delete> and it'll take away all the uneven extras.
