I started using Painttool SAI for my bases, so I have more controll. Also I love to make bases right now, but I don't have many ideas at the moment.
Just link me to an official picture from the side http://mlp.wikia.com/wiki/My_Little_Pony_Friendship_is_Magic_Wiki !!
I won't be doing bases of fanart.
Each Pony on the base cost 10 :points:, so three ponies cost 30 :points:.
If you want that a character stays normal. Example: You give me a picture of rincess Luna and Scootaloo. and you want that Luna schould stay Luna, you have to pay 15 :points: extra. So for the two Ponies 20 and that Luna stays Luna +15. =35.
Just comment me.
