When you create a sprite it is of the size 2 blitz units x 2 blitz units extending from -1,-1 to +1,+1.

You can use scalesprite to resize the sprite.

Furthermore you should not use a texture of size 56,84 because most video cards like power of 2 sized textures (not necessarily square though). So you may be better off using a texture that is 64x128 or 64x64 or 128x128 for the image you wish to use.

I would also suggest to use one of the already existing and free Sprite-based pseudo-2D solutions that are floating around frequently, example given:

or Draw3D
