EDIT2: @atheno (again) is there a reason the outline isn't all the same colour? (it's actually a very dark grey and black), alot of sprites use the dark grey so I suggest using the dropper tool to select the darkest colour on the sprite rather than using black 
True, although this time I thought it was black, and didnt bother to check. Another thing is why are you using the pt/hg/ss sprite? just like it better I guess 
Exactly. I still prefer HGSS, and on the whole I find the sprites look better.
EDIT3: 
The top doesn't look as flat and the screws look like screws. 
That's the idea?
