Ok, thanksNot bad, though the Beehives outline pixels are 2x2 while the inside ones are 1x1, which looks weird. The same thing with the Mega shark, the bullets are a smaller pixel size than the gun.
Here's something to remember:
Terraria sprites are scaled up to twice their original size, so each pixel is actually 2x2, so make sure you either shrink the sprite down to half before adding to it or use a 2x2 brush.
The Sniper rifle looks very decent.
