re-size pixel art

[lemoncas]

hi, I've done a portrait in pixel art, but its too small (90x110). Is there any way to re-size to make it bigger without antialising, keeping the pixels proportion? If not, how can I do a pixel art with bigger pixels in photoshop or pixen (i work on mac). I tried in phostoshop with bigger pencil but it doesnt works as good as with 1px pencil.
thanks

See this post from a recent thread.

Basically, in photoshop, go to Image -> Image Size and change the size by exact multiples like 100%, 200%, 400%, 600%, etc. of what you want it to be but have the sampling method be "Nearest Neighbor"
