There are a lot of sprites from third-party weapon mods used in my own project, and for a long time I've had a certain concern about one particular set of sprites. It originates from the widely-known Zen Dynamics partial conversion by Xaser. The sprites in question were originally used for a weapon with a flame-based attack. For that type of attack, the muzzle flash looks very appropriate:

However, the weapon used in my mod fires missiles instead of flame projectiles, and for that type of attack the flash looks kind of out of place. I wish I could make it look smaller and/or more "tame" somehow, but I'm no graphic artist and I've never made a single sprite myself or edited an existing one in such a way. If anyone can edit these sprites for me, your help will be greatly appreciated. Your name will also be added to the credits list file of my project.
Thank you very much.
