Using the same image of the SVD used by Taboo, I have cut bits and pieces out of the rifle to shorten it down by nearly 20%. It's still recognisable as the SVD, but a bit more manageable for Blockland. This was not done by image resizing.
Shaved off another 15 pixels. Should be more like 20% now. However It's still not enough to make it look good for a Blockhead.
