These are pretty good. There is not much to correct except the right pet is grey and has red eyes. I suggest making a higher definition decal for the eyes. I do not know what the red and white particles are behind both the pets so I cant comment, but for the pet on the left I suggest a tail and for the one on the right I’d suggest turning his body (face?) to black as red compliments black better and gives it a more sinister vibe. Otherwise great job!
These are very nice, I’d recommend maybe changing the colour of the effects on the left pet (maybe a teal - just to match the wings) Also, i’d recommend changing the transparency of the neon sections to a lower setting as the neon is quite bright.
Also, as everyone else has stated, changing the quality of the face decal on the right pet.
I think they look good for the style you’re going for, although I think that it would look better if the colors of the accessories on the pets fit better with the color of the pets, they kind of clash because they are so different from each other. Like ArcticStarfall said, I think you should experiment with the shape of them a bit. I know it’s supposed to be a simulator type pet but it might make your game stand out a bit more.
