First things first, I want to explain why I said REASONABLE. Some people make VERY crazy looking ponysonas that would take FOREVER to draw on a computer or paper. So, I think it is MUCH wiser to make a reasonable looking ponysona. I think it is cool to make them on PonyLumen's website.

First Change the body color and height/weight/head size. Also you can change the head type.
You can then add wings and/or a unicorn horn. Just scroll down slightly and you should get the option.
Step 1: Step 2: Hair and Lighting
Skip ears and eyes to mane and tail. You can browse the many hair options and such. Once you have chosen the style you like you can change the color to the one you wish for it to have. Then, if you want, you can change the lighting. I highly suggest Default 2. (the second image is in Default 2)
Step 2: Step 3: Cutie Mark and Eyes
If you go back to the first section (Body) and scroll down all the way you will find the cutie marks. You can choose the cutie mark of an existing pony, or you can upload a png file. Then go to the Ears and Eyes section. You can change the eye type, eye color, and its positioning. In my example I changed the pony's eyes to cow eyes and made it's pupils closer to the nose. I also used Vinyl Scratch's cutie mark (highly suggested for music artists/admirers)
Step 3: Accessories
Accessories are NOT necessary, but you can add them. Go into the accessory section and browse. Pick what you want and change the color if you'd like.
Step 4: Have Fun!
You can do many other things with this program, I was just naming a few. Have fun with the fan art and posing!
(It would mean the world to me if you left a <3 , so please do!)
