we're giving you criticism, it's not like we're calling you a cunt and telling you to kill yourself
if you want to make a CI you need to render the model in a sideways view and take a picture of it, preferably with snipping tool. then you edit as you wish but generally people prefer it to be red with a sharp black outline. you also want it to be small, in the size range of the pistol CI
I'm unfamiliar with blender so you should probably ask the 3D models topic on how to render your model.
