Adobe After Effects animation mods

Hello all I have a handful of Adobe After Effects animations that i need to size down and make into APNG (animated PNG) files. The files are about 2GB in size total. I will also need a few layers added (for night time) to some of them (i will provide). I have a list of all animations that i will need created by modifying the current animations: Some conditions can be Light, Heavy or normal, which has no classifier. For example, Light Drizzle, Heavy Drizzle, and Drizzle are all possible conditions. [Light/Heavy] Drizzle [Light/Heavy] Rain [Light/Heavy] Snow [Light/Heavy] Hail* [Light/Heavy] Fog* [Light/Heavy] Fog Patches* [Light/Heavy] Haze* [Light/Heavy] Rain Showers [Light/Heavy] Snow Showers [Light/Heavy] Hail Showers* [Light/Heavy] Thunderstorm [Light/Heavy] Thunderstorms and Rain* [Light/Heavy] Thunderstorms and Snow* [Light/Heavy] Thunderstorms with Hail* [Light/Heavy] Freezing Rain* Patches of Fog* (thin clouds with no sun/moon) Overcast* (just clouds with 10% transparent sun/moon) Clear* (no clouds just sun/moon) Partly Cloudy* (some clouds with sun/moon) Mostly Cloud* (more clouds with sun/moon) Scattered Clouds* (bits of clouds here and there with sun/moon) Funnel Cloud* (this is a tornado) Unknown (can just use a "?") * = animation needs to be created And FYI I don’t like the 3 clouds all together but I like the single clouds (see attached example) Here is a preview of those animations that i will be sending to edit:--> [login to view URL] Please only knowledgeable Adobe After Effect users need apply.
