Hello! These are looking great. Here are my opinions~
I don't really like the border tbh.
Try using more colors and brushes!
2.This one is the best out of all three imo. 6.5/10
The colors look pretty nice together and I like the square-ish patterns around her.
I like the font you used too, but I think it would look much better If you added some effects to it or w/e. You can try this if you want to:
Right click on the text layer > Alpha to Selection
At the top, hit Select > Grow (1)
Create a new layer
See the dashed line things moving around?
Pick a color and fill it with that color.
Here's a little shortcut: CTR+,
Now, make sure that the new layer is selected and make it "Overlay."
Ehh I don't really like the Shape/Border of this one also.
It's kinda pixely, and I think that the text might look a little better if it was larger and moved down a bit. I do like the flowery background, though.
It'd be great if you opened a shop!
Don't be afraid to take your time on these and play around with more filters and effects.
Great job! ❤
