month counts from first sub
First 3 - one grayscale clean sketch icon of chosen character for each (prepare reference and emotion!)
From 5 to 10 subs - two random subs will get lineart flatcolor icon
13 subs and more - gacha. Send me the character (or media series, we can use fan-art here) and I will roll the wheel for simple fullbody
for the 4th, 11th and 12th sub - do not worry, if there will be no one at the end of this month - I'll also make you a sketch icon: 4 - grayscale, 11/12 - color
