so i recently got my first drawing tablet, and ive been using mostly fire alpaca as an art program. Unfortunately, im having some problems with image sizes? If i make the picture small, then the lines tend to look kind of pixelated, but the avatar limit for wolfplay (to the best of my knowledge, im kind of new) is 300x300. im not sure how to make a avatar sized image in fire alpaca without the lines looking weird. do i need to make a larger image and then change the size later? how would i go about doing that? help?

I'd suggest using a multiple of 300. So 900x900, 600x600 or 1200x1200 and resize the final image at the end. Off hand I can't check how the lines look, but amongst those sizes you should be able to find something that you like? As long as you follow those proportions, in resizing the image there shouldn't be that much of a quality drop :)
