Here's the sketches of your OCs that you requested to me! I'm sorry for the delay, but holidays and references made me late! I hope you will like it and that I did honor to your OCs!
The characters are:

• Chernobog for DeathSeraph
• Vekter/Elysia for thelostsindar
• Kyte for Kaerlyn
• Grimm for DarlingV(she didn't requested him but I wanted to draw him anyway because is awesome!)

I used two colors to show some details and I really like the effect! I had fun doing this and I hope to do more sketches in the future!

Stay Groovy ;-)
