New to GZDoom modding

[T-MAX X-H]

Hello, my name is Tom. I began experimenting with modifying Doom 2 through GZDoom. I created my first (GZ)Doom 2 mod using on a custom weapon tutorial as a base. My main focus was to create a new shotgun using sprites made in my 3d animation program, DAZ Studio 4.8 Pro. I used Photoshop to resize the spawn sprite, which now looks kind of ugly. The mod is not perfect, but this is my first attempt at modding outside of making maps in Cube 2. I'm hoping someone will look at my mod and give me some advice on how to make it better. Thanks in advance.
