Been wanting to draw the 3 main alien species most commonly encountered is supposed abductions. These were fun, as I was in a documentary mood the other day and watched a buttload of alien stuff, haha.
From L to R:
Described as tall human-like beings, 6-8 feet, classical in appearance, and very european looking. They have pale skin, light blonde hair, very bright blue eyes and are often seen wearing skin-tight clothing. The Nordics are more often than not, pleasant. They warn others of the greys.
The Greys are the most common alien type associated with abductions, and get their name from their greyish green skin color. These guys are described as child-like in size, possessing disproportionate heads, and genderless. Their demeanor varies from different abductees, as they can be either neutral or hostile, more-so the latter.
Reptilians are the most hostile of the bunch, as most encounters with them are very unpleasant. Not much is known about them, apart from their appearance. They have swampy green colored scaly skin, a semi-humanoid face and slitted eyes.
