The first one has a mood-y effect. Like it. It just needs to be a little brighter.
The rest are very interesting too. How did you make the flames in the last image? Also, is this part of a story you are putting together? It looks like there’s a story waiting to be told here.
The flames are from Jepe’s Flames and Jepe’s Throws. I’m not organized enough to create a story. I am new at this and I like these hounds so decided to play around with them.
