I owe a few people some art and commissions, but I'm yet to get back to them, so here's the ones I can remember off my head.
OC and Natsu Dragneel (as a pony) hanging out like bros.
EQG OC Aiden, and EQG OC Ramone
The mane 6 stunned to find out that OC Harmony Star has turned into a mare.
StealthyMac (Bau): Shipping picture of OC and Lyra Heartstrings.
Chaddack (Bau): A picture of OC.
Labrat (Bau): Animated signature of Tacoshy.
Shcokwave (Bau): Signature 'For the glory of Celestia' overlaying Princess Celestia mane design.
If I've missed your commission please comment saying so.
